HDA sound driver mod for thinkpad x60s

It seems to load properly on my Acer Aspire 1641 (see the details 
-dmesg, etc.- here: http://www.mguillaud.net/acer1641/FreeBSD/ ).

This machine has a Intel 82801F chipset, I attach the diff to have it 
properly identified.
However, although applications seem to be able to play sound now, 
nothing can be heard at the output. I seem to recall that these chipsets 
need to be unmuted upon startup, which might be the solution here.

I'll try to have a look into the HDA spec 
(http://www.intel.com/standards/hdaudio/) about this muting issue...
Thanks for your work !
