I'm not sure what the uninstalling is about (maybe a mix-up with the
post_upgrade where it automatically tries to remove the loaded
module). In either case you don't need to reboot, after installation of
your custom package, logout then switch to another console ctrl+alt+F1.
Login then exec:
`sudo /etc/rc.d/kdm stop`
this should shutdown the X Server
as well then exec:
`sudo modprobe -r nvidia`
`sudo /etc/rc.d/kdm start`

And that should restart kdm...
