<pre>Side note, the world is moving towards backlight buttons generating input
events (via ACPI or otherwise) to userspace, and userspace using kernel
interfaces to adjust brightness. Eventually there will be no short circuit from
BIOS back to the kernel for backlight; indeed this is already non-functional on
some machines targeted at Windows 8.</pre>
