No, just that some like NPTL and ACL support are there.

No, sorry, none of the scheduling stuff is in RHL 9. For that, you would
need the RHEL kernel, or a real 2.6 kernel.

Yes, I'm also awaiting being able to use hyperthreading in a sane
way, so I feel your pain. But no go with RHL 9. You'll need to
upgrade either the OS or the kernel, as you previously noted.
