You don't need to be superuser by starting the realtime task and xrtailab. We 
implemented the line

        rt_allow_nonroot_hrt();

to allows normal users start real-time tasks. I checked the example on my 
system (2.6.7-adeos) few minutes ago and it works correctly.

Try to download all the rtai modules and reinstall them (this clean all the 
task names...).

Separately I send to you my script which loads the rtai modules.
