Subject: [PATCH] bcm5974-0.62: Compatibility mode reverted, BTN_TOUCH event
 added

The mousedev driver requires the use of BTN_TOUCH events to process
ABS_X and ABS_Y events properly, which is what is needed for the
bcm5974-based apple computers to have a functional pointer out-of-the-box.
This patch adds the BTN_TOUCH events to bcm5974.
