It can probably act as the dumber, non-synaptics touchpad, too.

I was asked to test if a recent change undoes a commit I made that was
kinda similar - when probing ALPS unsuccesfully, it set my touchpad into
a different mode, so I had to add a PMS_RESET command in the error path,
so it'd return to the dumb compatibility mode which doesn't need a
special driver. Havent done this yet.
