Yes. Put a touchpad section in the xorg.conf with the synaptics driver.
The synaptics driver is more powerful than the normal mouse driver and
will take care of the touchpad then. Usually touchpad events come as
/dev/input/mice as well, so the normal mouse driver processes them, but
I recommend an additional touchpad section.
