The short answer is no, if you still have the gateway laptop.

It works for you because it (your laptop) has active multiplexing. Without
active multiplexing I see no way of demultiplexing different mouse
protocols in mousedev.

A guestdevice behind the touchpad also needs demultiplexing even with
activ multiplexing. This could be done in the synaptics driver but as the
guestdevice can be any device, the synaptics driver needs to know every
mouse protocol there is to demultiplex it. The synaptics driver sent does
not demultiplex a guestdevice.
