Description of problem:
About once every two weeks, my desktop just stops functioning.  SSHing from
another box and doing 'top' shows Xorg utilizing 100% of one of my cpus.  

Next performing a 'gdb -p <pid of Xorg>' and 'bt' shows the culprit to be
NVSync.  This is about the 4th time I have hit this bug in about two months.  It
is starting to annoy me to the point I am creating a bugzilla (which I normally
dislike doing because its tedious).

Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.3.0.0-9.fc7
xorg-x11-drv-nv-2.0.96-2.fc7
xorg-x11-drv-nouveau-2.0.96-2.fc7
xorg-x11-drv-nvidia-100.14.11-1.lvn7
