The latest Planet CCRMA kernels use a different mechanism for realtime
access to non-root users. They don't have the kernel module so a warning
is printed but it is harmless (the capabilities needed are now part of
the standard kernel). 

I have read the thread but I still can't think of why this is happening.
Well, I have not had any time to think, to tell the truth :-)

The symptoms would seem to point to the video card as the culprit,
specially because X seems to be the cpu hog when running the "normal"
Fedora Core kernel. Could you try to use the non-accelerated standard
video card driver to see what happens? What driver are you currently
using?
