I have the backlight control keys working on 3.13.0-17 with the addition of the following to my /etc/default/grub file:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"

The backlight is controlled through the intel driver rather because the internal display is connected to that card rather than the nvidia.
