Bug reported by Chip Salzenberg on the Debian BTS a couple days ago, applies to
1.1.0 and current git.

My Thinkpad has a blue Fn button; when this is depressed, the Home and End
keys are supposed to control backlight brightness.  When the radeonhd driver
is active, these buttons have no effect.

However, the BIOS does seem to know they're being pushed, because after
switching to a text console, and pressing those keys once, the cumulative
effect of the previous presses is also seen.

Subsequently switching back to the radeonhd vt leaves the brightness at the
new (modified) level.  So essentially I have to switch to tty1 to change the
backlight brightness.

Config and log available at the URL above.
