I tried something different here.... does this tell you what I need to 
know?

david at test:~ $ lsmod | grep snd*
snd_ca0106             27172  3
snd_ac97_codec         72188  1 snd_ca0106

snd_pcm                78344  3 snd_ca0106,snd_ac97_codec,snd_pcm_oss
snd_timer              21764  1 snd_pcm

soundcore               9184  2 snd
snd_page_alloc         10120  2 snd_ca0106,snd_pcm

david at test:~ $ sudo modprobe -vn --first-time snd-ca0106.ko
