Hi!

Just tried this driver - I didn't know it existed before. I'd had troubles with
the synaptics support in GPM (pointer disappearing and reappearing, erratic
movement, etc). This driver doesn't appear appear to have those difficulties.

There seem to be a few issues on my Compaq Evo N160, however:

* the right mouse button doesn't generate any pointer events

* the four-way directional buttons all generate a button 5 press (is it
  possible to have it generate 5/6/7/8? or configure the buttons? I'd like to
  use one of the directions as a middle mouse button, and the others for a
  scroll-wheel type affair. As long as the numbers are independent then I can
  probably reconfigure the order with xmodmap.

* scrollarea doesn't seem to be picked up - do i need to fiddle with the
  boundries of the device? is there a convenient way to show the max extents of
  the device?)

* I also had to add the core pointer option to my settings - it might be nice
  to add that directive in the example in INSTALL

Thanks for the great work. :-)
