HDA sound driver mod for thinkpad x60s

[Andrea Bittau]

[i sent this to fbsd multimedia.  I noticed a discussion about sound on x60s on
fbsd mobile so I decided to send here too.  Lemme know if it worx.]

this is an ultra crude mod of Stephane's hdac driver.  It allows me to play
music [and change the volume; w00t!] on my ibm x60s laptop.  I posted it in case
anyone wanted a 0day sound driver for this laptop without having to wait until a
stable and proper version comes out.

Doesn't support recording.  I'll probably do that next if no one writes
something in the near future.

Stephane: if you are interested in me helping out with the "mainstream" driver,
let me know.  My time is very limited [you can tell by reading the code] but I
have all the info I need about this card in my head now, so I might be able to
produce something useful.

[I'm not subscribed to the list---email me directly if you need to contact me.]
