2.6.18-rc4-mm3 -- intel8x0 audio busted

[Miles Lane]

I haven't had working audio in 2.6.18-rc4-mm series (1,2,3).
I haven't been able to track down the cause yet.  The modules
all load, and there seems to be the expected enties in /proc,
but my sound preferences panel shows no available audio card.
