Humm, then why is everything running fine here, using alsa, on a 
via82xx chipset, an 8233 TBE.  Check your lsmod output against this:

Module                  Size  Used by
snd_seq_oss            32896  0
snd_seq_midi_event      7744  1 snd_seq_oss
snd_seq                51408  4 snd_seq_oss,snd_seq_midi_event
snd_pcm_oss            50792  0
snd_mixer_oss          18624  1 snd_pcm_oss
snd_via82xx            25860  2
snd_ac97_codec         65860  1 snd_via82xx
snd_pcm                92644  3 snd_pcm_oss,snd_via82xx
snd_timer              24964  2 snd_seq,snd_pcm

All this on a 2.6.8-rc1-mm1 kernel.

xmms runs fine, tvtime runs fine, I can play a cd or a realaudio 
stream from the net, and the sound is pretty decent.
