Maybe also this bug is related: https://bugs.freedesktop.org/show_bug.cgi?id=38718 "I can confirm that with Acer Emachines E527, it's quite same behaviour on all modern linux distributions (ubuntu, debian, gnome 3 livecd). Till 2.6.32 it works out of the box, after it I need to manually run setpci -s 00:02.0 F4.B=00 as root to enable backlight (completely black screen until gdm screen, very dim before running setpci).
