The reason for doing this was due to the fact that I felt adding
Sparx5 support only cluttered the original driver even more.

And since I was adding a new driver, I needed to add bindings for it -
and (re)move the old ones.

I have become aware of Serge and Wan Ahmad's work, and will work out
something on top of that.
