>Description:
              The synaptics touchpad that I am using (a newer version) has many features: tap and drag, horiz and vert scroll bars, a scroll ball and multifinger sensitivity -- to make two-finger tapping give the middle mouse button, for example. 

When hw.psm.synaptics_support="1" is set in loader.conf only the scroll ball works (buttons 4 and 5 mapped to z axis). I.e. no other features work. Moreover, xev shows all kinds of sporatic output that seems to be related to multifinger tapping and other features. In general, this makes the mouse very annoying.

If you leave syn_sup off, then you get tap-and-drag but no other features. 
>How-To-Repeat:
              set hw.psm.synaptics_support="1" in loader.conf, reboot. comment that hint out, reboot. The "support" consistently changes between the two types.
>Fix:
              It seems that with support turned 'on' the mouse is reporting more events but they are not getting interpreted correctly.
