We got it running! Using a 2.6.7-kernel and the hal6-patch of RTAI-3.1 
it works. Both user-latency and user-preempt-examples run. Starting 
xtrailab gives no kernel oops.

Now we can proceed in our work.

Many thanks to all, who helped us in solving the problem.

Greetings from Wuppertal and have a nice weekend
