[radeonhd] [Bug 13984] radeonhd: Thinkpad backlight controls do not work while driver is active

The buttons require bang the hardware directly via vga io space which the
radeonhd driver disables at the moment. You'd need to either enable the vga io
or if you can get events for the acpi buttons, bind them to xbacklight. Also,
I think the backlight can be controlled via an atom method as well, which may
be preferable as not all vendors control the backlight the same way. This
could be used with the bios scratch registers to keep the backlight in sync
between the driver and the bios. See atombios.h.
