You can put them into a special mode which allows you to do more stuff
with them (get absolute position and pressure information and the like).

There is a driver for X which does this, but it doesn't work on FreeBSD
because you can't tell our PSM driver to move asside (it insists on
sanity checking packets).

I got part way through hacking moused to grok my Synaptics touch pad,
but I got stuck because once it's in absolute mode the psm driver
doesn't like the packets it outputs and resets it :(

IMHO moused should do most of the work that psm now does, but I don't
have any patches yet :)
