To recap: the ALPS GlidePoint can in theory be used with a generic PS/2
driver, a generic ImPS/2 driver, or the advanced synaptic/alps driver.

If 0x73, 0x02, 0x64 is added to the alps driver, the kernel will use
this to talk to the touchpad. However, the touchpad uses a protocol that
is slightly different from the other alps touchpads, and we haven't
figured out exactly how it works. Because of that, when the alps driver
is used, all the fancy features will appear to be available in the
config screens, but will not actually work. Scrolling will not work
either.

The generic PS/2 driver doesn't support scrolling. The generic ImPS/2
driver does support scrolling. Until we figure out what protocol this
touchpad uses, we should fall back to these, and use the configuration
as described by Rocky in #78 to make sure ImPS/2 is used and scrolling
works.

Anything I can do to help figure out the protocol for the alps driver
with this touchpad?
