+     * XXX: This is largely guesswork.  The documentation from
+     * Synaptics doesn't mention guest devices, but it appears
+     * that packets from a stick are simple ps/2 packets...

They are ps/2 packets but if you are crazy you can send
the guest ps/2 device  some ps/2 commands to put it into a special
mode where can get features like pressure but well I don't know if
that is really needed. ;)
