I did a write-up a while back about how I did it.

I'm sorry, I can't quite tell what you're asking. If you're asking for a
way to enable edge scrolling without having a functioning touchpad
driver, I don't know of any. I doubt it's even possible to detect that
you're near the edge of the touchpad with only relative motion events.

I'm afraid it's just not practical to do this remotely. Being able to
physically interact with the touchpad is pretty crucial.
