You have to run jackd as root with a non realtime kernel to get realtime priority. But it will be rt in jack, not full premption as with a rt-kernel. The premption depend in all case on the kernel. With a non rt kernel, you will only get a higher priority when runing jack with rt priority.
If you read not only my last post on the forum with the test, but the other ones, I talk about compiling a vanilla kernel and testing pam-Rlimit with it. I get wird system behaviour as the whole system freezing to death with a low cpu usage. With the same 2.6.16 kernel, but rt22, all is working fine.
