Mattock > Well, here it could just be my ignorance, but I think last year when I was trying, I tried all possible pins and didn't find the mic anywhere. Then I thought that it could be some vendor parameters on 0x20, but then I saw the plist file in the kext and the only thing they adjust is the pindefault to 0x90a00110: [Fixed] Mic at Int N/A on what it seems to be either pin 0x1c (which I tried) or 0x27 (which is nonexistent). There's a thread at the ubuntu forums with people running alsa on air 2,1 but I couldn't get anyone to play with hda-verb.
