-commit d5ff9d8b0b186cf39695df84a10984eac559b746
+ Turn down the default sensitivity for unibody MacBook touchpads
+
+ The touchpads are too sensitive by default. A touch is activated when a
+ finger hovers a millimeter off the device. This change turns down the
+ default sensitivity so that accidental touchpad interactions are
+ lessened and pointer interaction accuracy is increased.

+ Add MODEL_UNIBODY_MACBOOK touchpad model for bcm5974 devices
+
+ Initially, treat them the same as MODEL_APPLETOUCH devices, as that is
