Normally, Synaptics touchpads use logic that (1) ignores large-area
contact, assuming it's an accidental touch with the palm, and (2) disables
the touchpad while the keyboard is active. If those measures are not in
place, there will be a problem regardless of tap-to-click.
I don't know where in the stack this logic lives. If that logic is
already active, then it sounds like further measures are warranted.
