I doubt that would help.

The mousepad can operate in two different modes, in the basic mode you
get built-in tapping, but only two buttons, in the other mode you get
more information (e.g. all buttons), but have to figure out the tap
action yourself from the pressure delta over time.

The behavior is documented by the manufacturer (synaptics.com.tw), who
actually provides specs on-line (whee!).
