As Philippe explained earlier, this won't work because Xenomai 2.4
required some deeper modifications to adopt the new clockevent subsystem
that came with 2.6.21 for i386. Those changes will not be backported to
the official stable 2.3 series in order to avoid regressions. But you
are free to do such a backport on your own - though I would rather
suggest to _first_ test 2.4-rc1 if it doesn't work as well (given that
it also includes the global affinity patch...).

Xenomai is the only true official user of Adeos/I-pipe. Still, there are
furthers as you may know: RTAI adapts the patches for its own use
regularly (but fails to cooperate on the development, even doesn't
report any glitches of the patches). And there is at least one user
group at Siemens A&D (Nürnberg) as you can grab from the archives. But
they changed the patches significantly and are probably yet on some
older kernel (2.6.15).
HTH,
Jan
