Alsaconf works, in that it detects the card, but then fails to find a
card for some reason.

supergrass orchid # alsaconf
modinfo: could not find module snd
modinfo: could not find module snd

            Following card(s) are found on your system.

Running update-modules...
Loading driver...
Starting ALSA.../etc/init.d/alsa: Error: alsactl restore failed with message 'alsactl: load_state:1134: No soundcards found...'.
Setting default volumes...
Saving the mixer setup used for this in /var/lib/alsa/asound.state.
/usr/sbin/alsactl: save_state:1061: No soundcards found...
 Now ALSA is ready to use.
 For adjustment of volumes, use your favorite mixer.
 Have a lot of fun!

My kernel has no oss enabled, compiled in nor as a module:

alsamixer says: 

alsamixer: function snd_ctl_open failed for default: No such device

and lsmod:

I will try booting with pci=noacpi next and let you know if that works.
