2.6.21-rc6, ASUS M2V 1.01G, ALSA detection/non-support

[Richard A Nelson <cowboy@cavein.org>]

My son has an earlier version of the M2V & BIOS (0901) and his gets full 6ch
sound.

The 1.01G, and related BIOS (1304 or 1701) do not properly handle the
onboard sound:
hda_codec: Unknown model for ALC660VD/ALC861VD, trying auto-probe from BIOS...

it seems to truely be a BIOS issue, as I don't see a difference in lspci
-vvxxx between our systems:

ALSA, instead of seeing ALC660, on my box sees ALC660-VD, with very
little in the way of devices (only front output) - which does not work
either :(

Stumped on where to go from here...
