As there haven't been replies to this thread from the others, I cc'd
everyone I know having the same problem on an ASUS M2400N.

As you wish:
pcm0: <Intel ICH4 (82801DB)> port 0xe100-0xe13f,0xe000-0xe0ff at device 31.5 on pci0
pcm0: <SigmaTel STAC9721/23 AC97 Codec>
That's on an ASUS M2400N as well. So far, sound works fine again.
