Well, the keyboard does handle a lot of it in HW. I only added a couple
of things in the driver, like fn-backspace or fn-alt (in fact, some of
them are also done in the driver in MacOS X).

It seems that the USB one is doing the entire stuff in software which is
a completely different scenario.

On a different note: I've seen a hacked trackpad driver for OS X that
implement the 2-finger scrolling with our current trackpads; and other
niceties. Basically, I found some interesting details about the
additional data the trackpad sends, like wether you haev 2 fingers,
wether you are in the center zone or the border zone, etc... that can be
used to implement various interesting features.
