linux$ uname -a
Linux oregano 2.6.26-1-686 #1 SMP Sat Jan 10 18:29:31 UTC 2009 i686 GNU/Linux

There are no particular kernel options, I think.  Only root=..., ro,
and quiet.

Ok, from the Grub menu I typed 'e' to edit the boot command.  In the
kernel line I added 'pnpacpi=off' after the 'root=...' option and
before the 'ro quiet' option, separated with spaces.  I then typed 'b'
to boot.  The first time it did not work but hung after 'Setting the
system clock.'  The second time it booted, but it didn't solve the
problem.  'alsaconf' does not work properly and there is still no
sound card in /proc/asound/cards.  

First remark: Isn't the option 'pnpacpi=off' option similar to turning
PnP off in the BIOS menu, as I tried earlier and it didn't work.  That
would be consistent.

Second remark: Even with 'pnpacpi=off' there was a 'Starting ACPI
Services.' in the boot sequence and an 'acpid stopped' (or something
similar) at the very end of the shut down.  I don'T know whether that
means that the 'pnpacpi=off' didn't work for some reason.

I don't know how to check that.  amixer and alsamixer wouldn't even
start.

Thanks a lot for your feedback and sorry for the delayed responses
from my side.  I have access to this laptop only occasionally, since
it is not mine but one of a friend and I have installed Linux for her.

Best wishes,

Laurenz.
