It should act exactly like synaptics as it shares common gesture processing code with synaptics kernel driver. Differences are initialization and fingers position extraction code (and bugs). But it is true if and only if it is used with moused and sysmouse protocol. x11-drivers/xf86-input-synaptics port definitely should not work as it disables kernel PS/2 protocol processing and use its own routines for decoding touchpad events. > Granted, all of this may be moot and not even possible.
