To my knowledge, you can't add functionality to the trackpad hardware
using drivers. To do that, you would have to add capabilities to the PMY
firmware, AFAIK, a procedure that is undocmented. The problem is if you
screw that firmware up (which is highly likely, since it's undocumented
bytecode), you won't be able to boot your system to undo the damage, and
you'd basically have to replace the main logic board in your laptop....
In other words, it's not a very good idea to try this.
Later,
David
