--- Comment #34 from Peter Hutterer <peter.hutterer at who-t.net> ---
don't get too hooked up on the dpi factor, that naming comes from mice that
have actual DPI. A trackpoint works differently, so if there is a different
base factor that we need (e.g. convert it back to a constant acceleration) then
we should do this in the code. Likewise the acceleration function assumes that
there is no built-in acceleration - some trackpoints seem to semi-accelerate
based on the pressure applied so it'd be worth looking at raw data
(evemu-record) first.
