To test it, start with either the alsa-driver-hg20061130.tar.bz2 or download the recent 1.0.14rc1 and follow these instructions:
tar -jxvf alsa-driver-<version>.tar.bz2 # <version> == hg20061130 or 1.0.14rc1
cd alsa-driver-<version>/alsa-kernel
patch -p1 <macpro.patch.1
cd ..
./configure --with-cards=hda-intel --with-debug=detect ; make ; make install
dmesg -c
modprobe -r snd-hda-intel
modprobe snd-hda-intel model=macpro
dmesg >dmesg.out
Send me a copy of dmesg.out along with any differences that you see. I may need to tweak which pins get enabled.

I'm happy to test any patches you come up with. Have you had a chance too cook up any patches for the Mac Pro HDA hardware? I fooled around with different models yesterday, and the "auto" model detects very few output channels (PCM, Front, Line-in), but correctly assigns the front channel. It's still incredibly quiet.
