You need the OSS compatible modules. They are called :
snd-mixer-oss
snd-seq-oss
snd-pcm-oss
(and maybe others).

Here is the relevant section of my modules.conf : as you can see, I
don't have the same sound card, so the snd-card-xxxx module is
different.

alias char-major-116 snd
alias snd-card-0 snd-card-via686a
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
options snd-card-via686a snd_mpu_port=0x300



NOTE : I have ALSA 0.5.7 compiled from source, since the version in
Slink did not
support my card. I had to tweek it a little to compile it on
Slink+Kernel 2.2.13
