Why do you think this is related? NPTL is the threading library (the
newer one, that is). I would imagine that semaphores are not implemented
in it alone? Or is that the case?

I have not built 2.6.x kernels for rh9. I tried at the very beginning
but there are too many small problems in all the kernel related tools. 

If you need 2.6.x I'd suggest FC3 at this point (or even FC4).
