I found this:
May contain the beginning of an answer (maybe :-)
It is related to the post from Len which included this URL:
([PlanetCCRMA] Jack and Intel 82801g Audio - Possible Solution for us)
Very good resource!
Look for "imac" in that file (maybe try "model=imac-intel-20"?)
Since links come and go, I wanted to let you know that the file referenced above (ALSA-Configuration.txt) is included as part of the tarball for alsa-driver (e.g., alsa-driver-1.0.16.tar.bz2) on alsa-project.org.
