Alex's patch is for those laptop whose BIOS only sends a notification to
DELLABCE when Fn keys are pressed. His patch simply translates these ACPI
notifications to KEY_RFKILL keypresses.

Correct if I'm wrong, but shouldn't his patch have no effects on your
laptop? If I'm not wrong, CRBT returns 2 on your laptop, so the input
device is not even created. Am I missing something?
