[Nouveau] nv_backlight non-functional on MBP 5,3 in EFI mode
Hello, On my MBP (booted with noaccel=1 due to https://bugs.freedesktop.org/show_bug.cgi?id=27501), the nv_backlight sysfs knob is non-functional (though modifying nv_backlight/brightness does change nv_backlight/actual_brightness). Recently a patch was submitted to LKML to create a brightness control for Apple computers with a gmux (https://lkml.org/lkml/2012/3/16/388), the created sysfs knob does work for me. Cheers, Shea Levy
