I'm not sure that I think a protocol handler is necessary unless I am
misunderstanding what you mean. The TrackPoint is nothing more than a
PS/2 mouse with 2 or 3 buttons that responds to an additional set of
commands. The extra handling has to do with middle-to-scroll which
could be done in userspace.

Aside from that the only time TracKPoint specific processing occurs is
when some property is being manipulated.

Do you still think a custom handler is necessary?
