I'm happy to report that a test kernel package provided to me by Stefan Bader now gives the following in /dev/sndstat:

Card config:
HDA Intel at 0xee240000 irq 17
ThinkPad Console Audio Control at EC reg 0x30, fw 79HT50WW-1.07

[...]

Mixers:
0: Analog Devices AD1981
29: ThinkPad EC 79HT50WW-1.07

The mixer is accessible using 'alsamixer -c 29', in read-only mode as expected.

Next will be to figure out how to get the desktop to pay attention to the status of this mixer.
