At least for me this solves the problem.
Agreed, this was sloppy, only fitting the DE2 I used for porting Xenomai over nios2 mmu-less, and I was just about to propagate this bug to the next patch... Yet another set of macro is involved (instead of na_*) with the new design I've been using lately for the nio2mmu port over 2.6.35, but at least they are consistent this time, wrt hrtimer/hrclock settings.
