>Description:
from my machine's /var/log/messages:

Apr 22 11:33:44 ryouko kernel: pcm0: <Intel ICH6 (82801FB)> port 0x3400-0x343f,0x3800-0x38ff mem 0xf01c0400-0xf01c04ff,0xf01c0800-0xf01c09ff irq 17 at device 30.2 on pci0
Apr 22 11:33:44 ryouko kernel: pcm0: <Unknown AC97 Codec (id = 0x41445378)>

and I can't use sound output.
 
so, I add entry for "Analog Devices AD1986 AC97 Codec" at ac97.c.

after apply this patch  my machine's /var/log/messages:   

Apr 22 12:49:39 ryouko kernel: pcm0: <Intel ICH6 (82801FB)> port 0x3400-0x343f,0x3800-0x38ff mem 0xf01c0400-0xf01c04ff,0xf01c0800-0xf01c09ff irq 17 at device 30.2 on pci0
Apr 22 12:49:39 ryouko kernel: pcm0: <Analog Devices AD1986 AC97 Codec>

I can use sound output, but sound from "LineIN" not "LineOUT", sigh.
