Could you run alsa-info.sh with --no-upload option, and attach the generated file?
Also, try either the latest sound GIT tree or alsa-driver-snapshot tarball:
  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
  ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz

I just compiled the new kernel 2.6.31 (gentoo-sources-2.6.31) and internal microphone works.

Thanks again.
