Sorry for the delay, I was busy with
http://who-t.blogspot.com/2018/05/x-server-pointer-acceleration-analysis-part1.html
which is somewhat related to this here.

Thanks for the test results, very helpful. Scaling this down by 8 works for me,
I'll try to figure out a generic enough patch that we can use together with a
model tag. Do we have any way of detecting this hardware in userspace or do we
need to enable this for each model manually?
