On a non-RIXI CPU I was able to boot the system, run a basic GUI
application, create R/W shared mappings to /dev/mem, insert/remove
kernel modules, run a broken program that dumps core, etc.

I guess it would be a good idea to make sure swap still works.  Didn't
try that yet.

Can you think of anything else that might exercise the bits that were
touched by the patch?  Were there any tests you ran during the
development of RIXI support which uncovered subtle issues?
