those are the latest steps I did, AFAIK it was the first commit after 2.6.31-rc5 as you said "The suspicious changes are the first one and the third one."
deadff1665491afce124a8ff83f00f784161f660 is first bad commit
Thanks! That's what I expected (and worried)...
What happens if you apply the patch below to the latest alsa driver (or 2.6.31-rc6)?

I tried the patch you have attached, it patched well (I checked it) but seems to not work
After make I tried to modprobe snd-hda-intel-ca0110 and I saw in dmesg:
hda-intel: Invalid position buffer, using LPIB read method instead. alsactl[8292]: segfault at 0 ip (null) sp bfa83f1c error 14 in ld-2.5.so[54c000+1a000] HDA Intel 0000:05:00.0: PCI INT A disabled
and after reboot:
HDA Intel 0000:05:00.0: PCI INT A -> GSI 38 (level, low) -> IRQ 38 hda-intel: spurious response 0x1102000a:0x1, last cmd=0x000000 hda-intel: azx_get_response timeout, switching to polling mode: last cmd=0x100f0000 hda-intel: Codec #1 probe error; disabling it... hda-intel: spurious response 0x1102000a:0x1, last cmd=0x000000 hda_intel: azx_get_response timeout, switching to single_cmd mode: last cmd=0x100f0000 hda-intel: no codecs initialized HDA Intel 0000:05:00.0: PCI INT A disabled
It seems something went wrong
It's not a right fix but a band-aid. With that patch, load with probe_mask=0x01 option.

uhmm... don't know if I'm doing something wrong but
modprobe snd-hda-codec-ca0110 probe_mask=0x01
says:
FATAL: Error inserting snd_hda_codec_ca0110 (/lib/modules/2.6.31-rc6/extra/snd-hda-codec-ca0110.ko): Unknown symbol in module, or unknown parameter (see dmesg)
in dmesg snd_hda_codec_ca0110: Unknown parameter `probe_mask'
probe_mask option isn't only for snd-hda-intel?
Yes. Load it like
modprobe snd-hda-intel probe_mask=0x01
The codec modules will be loaded automatically by that.

I did it too without success, hda-intel seems not to load automatically snd-hda-codec-ca0110
(dmesg) HDA Intel 0000:05:00.0: PCI INT A -> GSI 38 (level, low) -> IRQ 38 hda-intel: no codecs initialized HDA Intel 0000:05:00.0: PCI INT A disabled
