Hallo,
schaun mer mal was es so zu finden gibt im Netz der Netze
Linux on Toshiba Satellite A30 (A30-554)
Was funktioniert
Ethernet
8139too driver.
Audio
ALSA snd-intel8x0 driver.
Video
Summary: Works, minor restrictions
The XFree86 driver to use is i810, supported AFAIK 4.3.0 and up. The Intel 852GM DRI kernel driver provides direct rendering.
The first problem I encountered is that while 24bpp depth is advertised, using this mode causes some weird X problems, and when back in a VT, the VT graphics will be corrupt (still usable, but flickering horizontal lines). 16bpp depth works fine, perhaps this issue will be resolved in a future i810 driver version.
The second problem I encountered is while attempting to switch to S-Video output with the built-in button. It appears that no matter what, the display becomes corrupt on the TV and the LCD display when done from X. Doing it from console first, then starting X in 800x600 resolution works.
ACPI
Summary: Works, with some minor problems.
Supported kernel ACPI modules: AC Adapter, Battery, Button and Processor. Battery and AC information is correctly reported, and button/lid events are properly detected.
CPU Frequency scaling also works, with two different frequencies. On the default "performance" mode, the notebook runs at it's regular speed of 2500MHz. When set to "powersave" mode, the clock is scaled down to 1250MHz. The correct CPUFreq processor driver is the "ACPI Processor P-States" driver.
The only problem I have encountered so far is very ugly. When running battery monitoring dockapps (wmab and wmpower, so far), the system suffers from sporadic complete lock-ups. The entire system freezes, and no information is to be found in the logs after a reboot. This problem seems to occur only during periods of user inactivity (mouse, keyboard), ranging from 10 seconds to 10 minutes.
After some further work, I seem to have narrowed it down to the rate at which these programs access the ACPI files under /proc. They sit in a while(1) loop, and just suck the information out as fast as they can. With some throttling, the problems have cleared up. Here is a patch for wmab-0.3 that creates a #define in wmab.h that allows you to specify the interval of updates in seconds (5s works fine for me).
Power Management
* S1 - standby: Seems to work, but returns immediately.
* S3 - mem: Does not work. Enters the pm mode fine, but upon returning, the system seems to freeze (lcd never gets power back at all)
* S4 - disk: CONFIG_PM_DISK: Works, but NOT with X running. Whether you are in it or switched to a VT, resuming will crash your system.
I suspect the cause of many of these power management problems are due to device drivers in the 2.6 kernel not being converted to the new format yet (so says the kernel documentation).
Modem
Summary: Works, but no tones
The modem is a Winmodem. To use it, you must use a proprietary kernel module, accomanied by a userspace daemon. The driver I used is slmodem-2.9.4, available here. I tried the 2.6 ALSA patch provided, but upon modprobing the kernel oopses and modprobe segfaults. Oh well, they do describe it as "almost untested"...
The only thing I do not like, is not being able to hear the modem at all, when dialing, handshaking, or otherwise. There's something nostalgic about it.. 
Special Stuff
There is a kernel driver called "omnibook" that allows configuration of advanced features. This patch to the current (at time of writing) stable release (omnibook-2004-01-20) will allow the driver to correctly identify the machine. As well, here is a hotkeys definition for use with the driver.
Was soll dir dieser Text nun sagen ? DVD rein und los!
Tipp: Einige Toshibas machen Probleme mit der Tastatur.
Workaround : Die Datei /etc/sysconfig/sax bearbeiten und
KBD_BOUNCE_FIX='yes' eintragen
Have a lot of fun
