I also have a Synaptics touchpad which used to have plenty of similar
problems before, so that when I would boot NetBSD on it I would always
attach a mouse. Recently in -current there were two sets of changes,
in driver level and in X, which made it rather usable for me; one
still has to be careful, but it is much better than before.

One has to use -current, though.
