I have done a couple more tests using xenomai from subversion.  Here is a summary of all the results I have so far:

xenomai-2.2.2 (patched as described above): switchtest runs
svn/xenomai/trunk (r1586): switchtest runs
svn/xenomai/trunk (r1589): switchtest runs
xenomai-2.2.3 : switchtest fails

This is on my Fedora Core 5 (32-bit x86), linux-2.6.17.13 SMP, ipipe-1.3 (except 1.4 for 2.2.3), gcc-4.1.1, Athlon64 X2.

Hopefully this will help,
