I don't think that the driver that you linked to is actually using true multitouch. They would have provided pinch-zoom and rotate functionality if they had a true multitouch driver. Some older Synaptics touchpads can report the number of fingers touching the touchpad or the driver can use the width property to determine the number of fingers touching the touchpad. This is what is referred to as emulation.
