You could try a new package I released that will set the permissions for 
you. You can install:

   yum install planetccrma-rt-permissions

That will give high priority scheduling (up to 99) and 4G of memory 
locking only to users that belong to the group "jack-rt" (make sure you 
are in that group!)

Or:

   yum install planetccrma-rt-permissions-all

Which will give permissions to all users (might open security problems 
although I have not had that happen to me).

You will need to logout and login again to test if it works. I only 
tested the -all package on fc16 and it seems to work for me.

Let me know how it goes.
