You can probably find out what went wrong by looking at 
/var/log/Xorg.0.log, there should be information there on why X did not 
start.

Could you tell us a bit more about the drivers you are trying to use? Is 
this something you are compiling externally? 2.6.33.x is really old now 
and will definitely not have the latest drivers inside (obviously). But 
it even might not work with an external compiled module because it is so 
old.

Not much we can do except patiently wait for the next rt kernel patch... 
The problem is not that the rt patched kernel is not robust, it is just 
becoming too old for current versions of distros.

If you add the planetccrma-testing repository you could test drive a 
kernel based on 2.6.39.1 with threadirqs enabled, not as good as an rt 
patched kernel but maybe better than the vanilla Fedora kernel.
