The last couple of Ubuntu releases have not included

Ubuntu thinks no one needs one.
more likely, the latest ubuntu releases were based on kernels newer than
the latest available rt tree, which creates a very complicated situation
for distro maintainers.
with 2.6.39, most of the former rt patchset is now in mainline, and the
big kernel lock is gone for good. that means the situation should
improve a lot, and ease the burdon on maintainers of low-latency
optimized packages.
