T61, kernel 2.6.22-9: no sound out of the box.

I had working sound with ALSA compiled from the alsa-source Ubuntu package (version 1.0.14-1ubuntu1) with just three (rather than five) extra patches applied:

 - http://hg.alsa-project.org/alsa-kernel/rev/958b39f3e8dd
 - http://hg.alsa-project.org/alsa-kernel/rev/47ca87407c84
 - http://hg.alsa-project.org/alsa-kernel/rev/ca37aeeeb0ea

I got the patches from http://www.thinkwiki.org/wiki/AD1984.

Now with kernel 2.6.22-10 sound is gone again: lsmod shows that snd_hda_intel is loaded, alsamixer shows Master and PCM channels at 100%, mplayer -ao alsa thinks that it's playing, but no sound comes from the speakers or headphones. I haven't tried compiling ALSA again yet; I hoped this changelog entry from ./usr/share/doc/linux-image-2.6.22-10-generic/changelog.Debian.gz would improve matters:
