The patch doesn't apply cleanly to r230008; hdac.c.rej is 15661 bytes
in size (mostly the section which deletes all the manufacturer-specific
defines at the top of the file).

After fixing that per hand I was able to make a kernel with which sound
still works.  Here the relevant bits from dmesg:

hdac0: <NVidia (Unknown) HDA Controller> mem 0xfcffc000-0xfcffffff irq 18 at device 0.1 on pci1
hdac1: <ATI SB600 HDA Controller> mem 0xfe024000-0xfe027fff irq 16 at device 20.2 on pci0
hdacc0: <NVidia GT21x HDA CODEC> at cad 0 on hdac0
hdaa0: <NVidia GT21x HDA CODEC Audio Function Group> at nid 1 on hdacc0
pcm0: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> at nid 5 on hdaa0
hdacc1: <NVidia GT21x HDA CODEC> at cad 1 on hdac0
hdaa1: <NVidia GT21x HDA CODEC Audio Function Group> at nid 1 on hdacc1
pcm1: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> at nid 5 on hdaa1
hdacc2: <NVidia GT21x HDA CODEC> at cad 2 on hdac0
hdaa2: <NVidia GT21x HDA CODEC Audio Function Group> at nid 1 on hdacc2
pcm2: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> at nid 5 on hdaa2
hdacc3: <NVidia GT21x HDA CODEC> at cad 3 on hdac0
hdaa3: <NVidia GT21x HDA CODEC Audio Function Group> at nid 1 on hdacc3
pcm3: <NVidia GT21x HDA CODEC PCM (DisplayPort 8ch)> at nid 5 on hdaa3
hdacc4: <Realtek ALC889A HDA CODEC> at cad 0 on hdac1
hdaa4: <Realtek ALC889A HDA CODEC Audio Function Group> at nid 1 on hdacc4
pcm4: <Realtek ALC889A HDA CODEC PCM (Rear Analog 7.1/2.0)> at nid 20,22,21,23 and 24,26 on hdaa4
pcm5: <Realtek ALC889A HDA CODEC PCM (Front Analog)> at nid 27 and 25 on hdaa4
pcm6: <Realtek ALC889A HDA CODEC PCM (Rear Digital)> at nid 30 and 31 on hdaa4

I particularly like that the messages now show which jack corresponds to
which pcm - makes deciding which jack to use much simpler.

I'm using pcm4.
