Alps touchpad driver for X-input (synaptics alternative)

Hello Peter,

Your arguments are valid.

The problems with the synaptics driver on my ancient UMax ActionBook are:

+ Using the touchpad, the cursor cannot reach parts of the screen,
  mainly the bottom. It may be fixed by smart configuration,
  but it is not easy to do for each operating system upfrade.

+ Using the touchpad, the cursor moves 'too quickly' and difficult to
  place into an exact pixel location.

+ On that slow and low memory machine, the driver seems to use too much
  resources.  That was another reason, I wanted to avoid dependencies 
  on 'finger movement speed' and floating point calculations.

+ On current Ubuntu, it is not easy to configure. The GSynapyics tool
  warns (and requires(?)) settings in /etc/X11/xorg.conf
  while current configuration happens under /usr/share/hal/fdi/...
