This problem still exists in Trusty with current Nvidia driver and Macbokk 5,1. I had to manually edit xorg.conf to make backlight working.

I had to manually edit xorg.conf to make brightness adjustable. In the "Device" section I had to add Option "RegistryDwords" "EnableBrightnessControl=1": Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce 320M" Option "RegistryDwords" "EnableBrightnessControl=1" EndSection I'd expect brightness to work "out of the box" after installing an nvidia driver.
