It would seem

quite easy and there's already lots of redundant code there, but possible problems arise from being able to work with both the old unmerged kernels and the future merged arch kernels.

Would the issues be located at the Adeos level, or would this leak to Xeno's arch-dep layer?

I suppose adeos level should go nicely with the kernel changes once they're in place; we can easily mimick the kernel techniques (#ifdefs) to tell which arch we're on. The issues would be with Xeno having to distinguish the kernel were building for. I'm quite sure putting all the Xenomai stuff under a common powerpc and having a few #ifdef __powerpc32/64__ won't be enough. Having SAID that, it probably will enough, though :)
