It seems there's just a bit too much oddness going on. Takashi, you know more about ac97. Also bringing in alsa-devel...

Eep? A 0x83847605 would be a SigmaTel STAC9704. And:
[ ... ]
# cat /proc/asound/AudioPCI/codec97#0/ac97#0-0+regs=
[ ... ]
0:7c = 0000 0:7e = 8384
does't fit the above ID. Do we just have a crummy codec that needs delay between acceses somewhere or something?
