Jonathan R, can you (or Colin G) comment on the patches applied
immediately prior to Maverick's release that purportedly resolved this
symptom?  I'd really like to avoid extending the already-awful
blacklist junk that we ship in alsa-base.

This is a driver bug.  Please file a bug against alsa-driver using
"ubuntu-bug alsa-base", please.

Maverick's kernel seems to support many VM applications just dandy.
Do you have the build log from a failed attempt?  Please file a bug
against linux.

kvm and vbox certainly work.

This has nothing to do with PulseAudio.  It's related to bugs exposed
by the kernel, yes: it could be faulty hardware and/or broken kernel
