Hi, it the SATA bug seems to be this one:

I could make the ata errors occur less frequently by adding a line with  
the entry
  ahci
to the file /etc/modules. Those freezes didn't go away completely.

I had to do another thing to prevent the nvidia driver to hang my system
when switching to the text console - disable the framebuffer.
Look for a line in /boot/grub/menu.lst starting with:
  # defoptions= ...
and change it to:
  # defoptions=quiet video=vga16fb:off video=vesafb:off

Afterwards you have to type "update-grub" to update your boot menu.
Note: All actions as user root. It will disable the graphical boot.

What might interest you is that the wireless driver of the 2.6.15-26-686
kernel started to work fully with a WRT-54G and a Dlink DWL-650g after
I downloaded and installed all of the Acer updates for the preinstalled
Windows XP.

What a strange experience.

I also had problems with audio during video playback with xine. I had
switch xine to use the OSS emulation from the ALSA driver and to create
a file ~/.asoundrc with the content
pcm.dsp0 {
     type plug
     slave.pcm "dmix"
}
# mixer0 can stay unchanged, because
# it isn't used anyway, I guess ;)
ctl.mixer0 {
     type hw
     card 0
}


I hope there will be a kernel release fixing those nasty SATA errors.
kernel-2.6.17-2-686 from edgy does not even boot.

What else does not work:
   - Logitech webcam, but I read somewhere that a driver for the Logitech  
webcam
     integrated in this notebook is in the works:
     ~$ lsusb
        Bus 005 Device 002: ID 046d:0892 Logitech, Inc.).
   - TI card reader
     ~$ lspci
        0000:0a:06.0 CardBus bridge: Texas Instruments: Unknown device 8039
        0000:0a:06.2 Mass storage controller: Texas Instruments: Unknown  
device 803b

Cheers,
Christian

PS: Doom3 is perfectly playable with OSS audio output on a resolution of  
900x600.
     Here is a modline (/etc/X11/xorg.conf file, section "Modes")for it:
       Modeline "960x600" 45.28 960 992 1160 1192 600 612 618 631
