Well yes its possible that my scheduler is better at hiding some bug. It
wouldn't be fixing anything, of course. It definitely was better at
exposing a kernel or postgresql bug when running OSDL's PostgreSQL tests -
I saw the crash 3 times I think, though never with standard kernel.

I don't know how you should be reporting X crashes. I guess you could report
the bug to the XFree86 guys as per their guidelines if you can reproduce the
crashes with an up to date 2.4 kernel.
