I really don't know; I run Debian (and self-built stock Linus kernels at
that), but reports on the list are that even disabling selinux is not
sufficient to allow SUID root mythfrontend to work its realtime priority

If you're up for building your own kernel, I'd highly recommend the new
realtime scheduling options in the newest kernels (2.6.12-rc3 and up).
It's currently pretty far from a pushbutton install though, as you'll
also need an updated PAM (all the info is in the links from my original
posting I referenced in my last msg).
