Comment # 4 on bug 1140244 from Stefan Dirsch

Ok. It's pretty hard to figure out what exactly happened here during the
update. Still the best for the update is getting rid of all NVIDIA packages
during update, then add again the new NVIDIA repo for the new distribution and
reinstall the driver that way. Otherwise you may have a no longer working
kernel module after the update to the new kernel. Switching to a newer driver
family doesnt' make things easier here.
