Simply calling "make" on the tree catches all dependencies on 2.6. If
you repatched the kernel, then you may see a full rebuild then.
Normally, a prepare-kernel is safe enough to catch potentially added new
Xenomai files.

Philippe does so regularly, and if you look back in Xenomai's history,
you will find *a lot* of maintenance releases for previous series. The
2.3 is fairly new, and so far the critical mass for a patch release was
not reached (no mission-critical bugs - though I see your issues can be
quite annoying).
