I have seen that but Brett's latest synaptics commit mostly fixed it for
me. Before that, I had

hw.synaptics.finger_scroll-max=14
hw.synaptics.finger_scroll-min=13

in my /etc/sysctl.conf, see pms(4) for an explanation of the various values.
This certainly needs more fine tuning, but seems to differ a lot between
various devices, so is quite hard to debug for a developer with a single
test notebook ;-)
