IMHO, it is meant to be a precision device, even though a cumbersome one.

The problem I saw on the machine I tested it on was that we don't get events
around the very dead center of the trackpoint. We only get them once it's past
a certain threshold, and by that time the pointer is supposed to move very
fast.

I can't debug this further as I no longer have the machine, sorry!

That looks like they just got rid on an old hack. It didn't allow interactive
speed changes like the TrackPoint driver does (trackpoint.c).
