A new input device will be detected and you will be able to read +the mouse data from /dev/input/mice (using gpm, or X11). + +In X11, you can configure the touchpad to use the synaptics X11 driver, which +will give additional functionalities, like acceleration, scrolling, 2 finger +tap for middle button mouse emulation, 3 finger tap for right button mouse +emulation, etc. In order to do this, make sure you're using a recent version of +the synaptics driver (tested with 0.14.2, available from [2]), and configure a +new input device in your X11 configuration file (take a look below for an +example).
