This is a standard fc kernel, you will (should?) not be able to run jack
as a non-root user with realtime scheduling...

What kernels do you have?
  rpm -q kernel
Do you have planetccrma-core installed?
  rpm -q -a | grep planetccrma-core
The latest and greatest Planet CCRMA kernel on fc4 should be:
  apt-get install planetccrma-core-edge
(for up machines)
or
  apt-get install planetccrma-core-edge-smp
(for smp machines)

Try those kernels (it should bring 2.6.12-0.21.rdt) first.
