--- Comment #3 from Marc Milgram <mmilgram at redhat.com> ---
I saved a copy of all the *brightness* files from under /sys when I booted a
3.13 kernel and compared it to when I booted a 3.14 kerel.  The following is
the only one that changed:

diff -r
3.13.10-200/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight/actual_brightness
3.14.4-200/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight/actual_brightness
