[Ricky Campbell <cyberdork33@xxxxxxxxx>]

the bcm5974 kernel driver is a low-level hardware driver that should
only provide for the hardware to send any signals to the OS at the most
basic functions. detecting how many fingers touching, detecting position
of touching fingers, and whether or not the button is "clicked". Pretty
much anything else that uses this raw information to perform more
advanced functions should go in an xorg driver (synaptics).

I hope this better explains the difference.

Bug description:
Within Mac OSX i can physically rest my thumb at the lower portion of the trackpad. While the thumb is resting there and not moving I can move my finger around above it to move the cursor and click with my thumb as needed. This makes the touchpad act as the old maclaptop that had the button there. I can tell they actually disable touching down there during this time cause as i move the finger above, if I then move the thumb it takes about 2 seconds to register the thumb moving.

With the latest bcm5974 (1.14) if I rest my thumb on the lower portion of the touchpad any finger movement above does not register.  Only one finger or thumb can be one the touchpad at a time to get cursor movement.
