Ok, I got this sweet MS Optical Trackball.  It works great with X 4.0, but I
can't get more than 2 buttons to work.

Anyone know an easy way to figure out how to get the rest of them to work.
It's actaully 7 buttons, 5 that you press, and a scrolly wheel.  I assume I
have to add things to the XF86Config file, but I'm not sure what to add yet.
I'm using the ps/2 protocol, maybe I need to change it the the Microsoft
protocol, and I also heard that some MS mice like the Logitech protocol
better also.
