I like the idea of this one, and have found it extremely handy already
trying to get my new Lenovo laptop (sadly, without dedicated trackpoint
buttons), somewhat usable.

But it's not clear to me from the above documentation whether things
like two-finger scrolling are disabled in mode 3. It would be handy for
me, personally, if not. That is, I would prefer to have no cursor
movement, ever, but it would be handy to still have two-finger
scrolling.

In my testing of this patch, it seems that the scrolling is disabled as
well, and that's unfortunate.

It's not clear to me if its appropriate to override this single
"TouchpadOff" variable for all of these modes. Might it be easier to
satisfy users with independent disables for each thing? (Dont' we even
already have enables for things like tapping and scrolling?)

So maybe all that's missing is a disable that affects cursor movement
and nothing else?

-Carl
