Bug#537599: gnome-power-manager: Brightness incorrectly reported as 100% on Thinkpad X200T

[John Sullivan]

Package: gnome-power-manager
Version: 2.24.4-3
Severity: important

g-p-m says brightness is at 100% (both while on and off AC), but
the screen is obviously not at 100% brightness, judging by
comparison to before I installed g-p-m. I'd estimate it at no
more than 80% of the actual max. When I use the thinkpad
brightness keys, the pop-up also claims that brightness is
already at the max, as does the brightness applet. Adjusting
brightness down, though, works as expected. The ceiling is just
artificially low for some reason.
