Just a few minutes ago sound stopped working (that was after a resume from S3,
but not immediately after it), without anything suspicious in dmesg etc.
Restarting X fixed that.

Still, that doesn't happen very often and it is not readily reproducible.

Well, that may be a pulseaudio problem, but the very same pulsaudio apparently
 worked well with 2.6.29-git<something>.  That might be a coincidence, though.

Yes, it appears to work.
