Great. Been reviewing this a bit today. Questions:

 - What changes have you applied in it - git tree? The mouse drivers
don't seem to be modular...

 - Is the xset command change a good idea even without kernel/driver
changes? Or only with them?

So, not much I can do with a modest effort. Disabling tap-to-click can
only happen with the synaptics driver, and that is a longish road.

So you mean CONFIG_MOUSE_PS2_SYNAPTICS=m and that combined with an
xorg stanza? Or a udev rule? Or just inelegantly renaming the kmod?
