The short answer is no, if you still have the gateway laptop. On 12 Jun 2003, Peter Osterlund wrote: > It works on my computer at least.

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. Peter
