Xenomai is not supported over distro-patched kernels. While some of
their patches may be orthogonal, other may have all kinds of side
effects together with I-pipe that no one wants to track down (not that
those patches are inherently bad, just not tested against I-pipe).

If you are missing a specific feature, either port it back carefully or
wait for it to appear in the next upstream kernel (e.g. AppAmor is now
in 2.6.36, and I guess we will have I-pipe for that kernel within the
next weeks).
