Specifications and infos:
The notebook uses a VIA KT133 (Twister?) chip set. There are many hardware description sites - every with little differences.
Here is the Maxdata specification: a copy from Maxdata.at
Here is the output of lspci:

When i was looking for informations about VIA KT133 and Linux i found a site which contains infos about Linux on a Compaq Presario 700EA (by Francisco Castanheiro) (this link is a COPY to avoid a dead link - click here to get the original homepage). I was really happy because this Compaq Laptop also got a via kt133 twister - and so i thought this description will fit on my laptop too ..... but it did not (not exactly)
how i set up X
just installed version 4.3.0 from the binary distribution from XFree86.org
using the generic savage driver works properly with my box.
Here is my XF86Config-4 file.
For the very nosy people my XFree86-Logfile: XFree86.0.log
settings up the framebuffer device
while kernel-configuring you'll have to enable VESA-framebuffer...
Sooo use VESA framebuffer and insert the following line in your /etc/lilo.conf and you'll enjoy seeing Tux everytime you boot your machine... (0x317 is for 1024x768)
vga = 0x317
Sound
While configuring the kernel i just selected
<*> VIA 82C686 Audio Codec
[*] VIA 82C686 MIDI
sending files to /dev/dsp and playing on /dev/dsp with WMMS works:) - but i don't know if the mixer is working (didn't try)
Don't forget to change permissons of /dev/dsp (for all users) if you want other users than root playing some nice songs.
Kernel-message while booting:
ac97_codec: AC97 Audio codec, id: VIA97 (Unknown)
via82cxxx: board #1 at 0xE400, IRQ 9
PCMCIA
i got no PCMCIA card to test (and no use, cause everything i need is on board:)), but i (seem) installed the pcmcia device with selecting following device while make my kernelconfig
<*> PCMCIA/CardBus support
[*] CardBus support
Network
In the Compaq description it seems to be a Realtek|RTL-8139 - but this driver did not work in my case.there is another driver for this card called via-rhine (supported my the kernel)

If you want to change or see your media interface status use the program mii-tool - for Debian users there is a package called (surprise) mii-tool - or get infos at http://www.scyld.com/network/via-rhine.html.
ACPI
aahhh .. here comes the real interessting stuff :)
This notebook is one of the "real ACPI-based" ones ...
Compiling the kernel with all ACPI options on is good, but not best --- the PowerNow feature won't be use..
You'll have to use the cpufreq patch! Get this at http://www.codemonkey.org.uk/projects/cpufreq/
After compiling the kernel with cpufreq you'll need the cpufreqd to watch and act .(throttling down you cpu-frequency)
applying some of these patched didn't work....so try some of them...
After having a patched kernel your bootmessage should look like this:

get your cpufreqd at http://sourceforge.net/projects/cpufreqd/. Because i use Debian Woody i had to compile it ..(binary package need some new glibc version oder some spooky stuff like that). now cpufreqd helps you to save power ... (if i'm not plugged it switches to 500mhz)
the only thing thats missing now is "sleep"-mode or "suspend"-mode. In kernel 2.4.* those modes are not supported .. so i tried it with kernel 2.6.3 (read more on bottom of this site)
Modem
I tried many many drivers for the modem. The driver written in the Compaq Laptop Howto didn't find my modem (but it should have) :(
But i found another driver :)
Its called PCTel Winmodem hosted by Sourceforge http://pctelcompdb.sourceforge.net/. Installing the driver was very simple - i think you just have to have your kernel-source & headers installed.
After installing wvdial will find your modem !
ieee 1394
i just tested firewire with an external ide-harddisk, but it worked !
while configuring your kernel you'll have to compile the following modules:
ieee1394
sd_mod
sbp2
ohci1394
sg
(some SCSI generic stuff & SCSI Disk module)
After running a small script - rescan-scsi-bus (i found on the internet) your external partitions can be found on some /dev/sda* devices. Mount them an use them ....
the most important files (again)
i tried kernel 2.6.3 to get better acpi support. one good thing is, that you need not to patch cpufreq into the kernel..it's already there
but sleep/suspend modes didn't work properly...so i installed a patch from http://acpi.sourceforge.net/.
but first some basic things:

ACPI
there is no S1 sleep-mode (like window$ uses it) available in linux ---so
suspend-to-disk (S4)
after applying a patch from http://acpi.sourceforge.net/ suspend-to-disk worked. (with strange messages, but it did)
how to do this:
echo "4">/proc/acpi/sleep
after that your computer shuts down...after rebooting it should resume from a partition mentioned in the kernel-boot-paramenter ...in /etc/lilo.conf under your image=...linux2.6.4
append="pmdisk=/dev/hda5 resume=/dev/hda5"
(hda5 is my swap partition)
while compiling the kernel you can enter this disk there too (can be overwritten with kernelbootparameter)
read more about this in your kernel documentation....
suspend-to-RAM (S3)
would be
echo "3">/proc/acpi/sleep
after some messages and filling the screen with WHITE? the computer falls in sleep-mode. waking it up by pressing "any key" it writes strange messages an hangs :(
ERRORs with 2.6.3
the only things thats strange with kernel 2.6.3 is under X...my ps2-mouse and/or touchpad seems to have probems
Feb 25 23:38:08 beatle kernel: psmouse.c: Wheel Mouse at isa0060/serio4/input0 lost synchronization, throwing 3 bytes away.
i didn't get a workaround for that. i tried to use "bare,imps" protocols for the psmouse-module but ...nothing changed
some files
