Yes, should be OK in 2.6.32, and broken by this commit:

ALSA: hda - Overwrite pin config on intel DG45ID board.
The pin config provided by BIOS have some problems:
0x0221401f: [Jack] HP Out at Ext Front <-- other association and sequence
0x02a19020: [Jack] Mic at Ext Front <-- other association
0x01113014: [Jack] Speaker at Ext Rear <-- line out (not speaker)
0x01114010: [Jack] Speaker at Ext Rear <-- line out
0x01a19030: [Jack] Mic at Ext Rear <-- other association
0x01111012: [Jack] Speaker at Ext Rear <-- line out
0x01116011: [Jack] Speaker at Ext Rear <-- line out
0x40f000f0: [N/A] Other at Ext N/A
0x40f000f0: [N/A] Other at Ext N/A
0x40f000f0: [N/A] Other at Ext N/A
0x40f000f0: [N/A] Other at Ext N/A
0x40f000f0: [N/A] Other at Ext N/A
0x01451140: [Jack] SPDIF Out at Ext Rear
0x40f000f0: [N/A] Other at Ext N/A
just overwrite it.

Yes, model=intel worked before.

It has to be assigned case by case, since we never know whether the
current settings will apply automatically to future Intel boards..
