I don't know if there are builds available for SL, but there exists a
Realtime kernel for RHEL6.  On Red Hat certified hardware, it should
provide a fairly comparable performance as the stock RHEL6 kernel, with
max latency less than 150µs and std.dev less than 5µs.

It's based upon the PREEMPT_RT patchset, but with a fairly newer kernel
base than the stock RHEL6 kernel.

If you can get hold of the SRPMS, it should be fairly easy to do a
build, even using mock.
