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?
We run the LTP, I think it tests these things. We also have a small test case that tests for both the no-read and no-execute parts, but that would be expected to fail on platforms that don't have RI/XI bits.
