The above error means that the kernel module that is currently loaded is 
the old one while the X driver is the new one.  In other words, you only 
tried to restart X instead of rebooting the machine or terminating X, 
doing "modprobe -r nvidia" and then restarting X.

Contrary to other posts, you do NOT need to rebuild your kernel.  You 
only need to load the new kernel module.
