Ubuntu's ports are known to be a bit buggy.. I wouldn't recommend those.

Novell/opensuse forward-ports are better.. they're shipping those patches 
with SLES11 (Suse Linux Enterprise 11) and with OpenSUSE kernels.

Patches exist up to 2.6.31 currently.

Those patches also work for domU, not only dom0.
