After working very closely with Dell. They have now completely changed
the way they have implemented there touchpad hotkey for upcoming
machines.
It now only generates a single keycode (0xD9). It nolonger does anything
in hardware, nor does it generate more then this keycode.
This patch properly maps this keycode.
