Updating Xorg on FC2

[Tim Wunder]

Has anyone updated Xorg on FC2 and lived to tell about it?
I'm currently running FC2 with
$ rpm -q xorg-x11
xorg-x11-6.7.0-11
and am experiencing occasional X lock-ups (well, technically, X is just 
using 99% of the CPU, so it's not "locked up," it's just running really, 
really slow).
Nothing in the .xsession-errors or /var/logs/messages files indicates 
(to me) what the problem might be, but I'm thinking that an update of X 
may magically "fix" things.

Any other thoughts on more useful ways of troubleshooting why X 
occasionally will use so much CPU would also be helpful.

Thanks,
Tim
