Attempt to make the ACPI hotkey support a little more modesetting-compatible.
Previously, we watched for the BIOS to have changed the layout, and repaired
the resulting configuration. Now, we request that the BIOS make no changes,
but leave a note in a register for when the key has been pressed. When we
notice this, we reprobe monitors and turn on/off the things we find.
This is a temporary solution until we can get the hotkey hooked up as an
input key to external applications to control the change using RandR 1.2. It
is also untested as neither of my laptops do anything with the hotkey.
However, this code does result in many fewer BIOS calls.
