Very strange. I take it you have not edited /etc/modprobe.conf, right?
Kudzu (or whatever) configured snd-darla20 as some kind of video stuff
(I think that is what happened, not completely sure). And it left an
"install" line for the a snd-intel8x0 soundcard behind (is this what you
have in your motherboard? have you turned it off in the bios?)

Try replacing the "alias char-major-81 snd-darla20" line with:

alias snd-card-0 snd-darla20

Then do an /sbin/depmod -a 
The try restarting alsa with the alsasound script:
  /etc/rc.d/init.d/alsasound start

Do you see any hotplug related messages in /var/log/messages or in the
output of dmesg?
