this seems to be (at least partially) the same issue that fedora was facing:

  https://bugzilla.redhat.com/show_bug.cgi?id=486525 

pulseaudio apparently attempts to grab 64MB of ram, and fails if there's not
enough. adding "disable-shm = yes" and "shm-size-bytes 1048576" to the
/etc/pulse/daemon.conf appears to fix that.

additionally, newer versions of pulseaudio need write access to /var/lib/pulse,
which isn't writeable by default (it's not even present). should be easy enough
to add, either at boot time or in an ltsp-build-client plugin.

and if that wasn't enough, it appears that pulseaudio reads
/etc/default/system.pa, which attempts to load module-hal-detect by default and
other modules.  well, that causes it to fail to start. removing system.pa seems
to resolve the issue. not really sure how to cleanly handle that.

live well,
