See http://fedora.redhat.com/docs/udev/ for the detail (down at the
bottom).  The quick answer: Boot to run level 3 (or wait until 5 fails
and you drop to a virtual console), reinstall the nVidia driver
(perhaps not needed) then issue the commands:

modprobe nvidia
cp -a /dev/nvidia* /etc/udev/devices
chown root.root /etc/udev/devices/nvidia*

By the way, this issue has been dealt with many times on this list. 
I'm not a big fan of saying "search the archives" (that's a huge
archive), but perhaps you could have found your answer there.  I won't
complain too much, though, especially since you just joined.  Just so
you know, this is a very high volume list, so be prepared for a lot of
messages : ).
