I've done some testing, and the short update is "it's working fine for me".
I love having two-finger scroll support!

A few more testing details added to the bug report.

Vladimir: Thanks for porting this from OpenBSD!
Thanks to the OpenBSD developers stsp, mpi, jcs, shadchin for the initial work on this [1].
Raphael: Thanks for ensuring this was captured in Bugzilla and for porting to 10-STABLE.
Adrian: Thanks in advance for your testing and help!
