By any chance, in any near time could be possible to boot UEFI + propietary nvidia drivers?
OK, there is a solution tested on FC18.
Download bumblebee and bumblebee-nvidia (https://fedoraproject.org/wiki/Bumblebee
see how it fails with just the instructions (April 22, 2013). Remove the /etc/sysconfig/nvidia/*310.32run driver, download the 310.44.run in that directory
Execute the failed bumblebee service
systemctl bumblebee-nvidia start
