I just did a short test, and got the following results with RTAI-3.1:

1.) kernel space examples run
2.) user space example "switch" also runs 
3.) "latency" -test in user space runs but gives the rather strage result: 
"*** min: 1073825388, max: 1 average: 0  <Hit [RETURN] to stop> ***"
4.) "preempt"-example still gives kernel divide error.

So the problem still remains in RTAI-3.1.
