In /etc/sysctl, conf, the setting hw.psm.synaptics.min_pressure=220 should cause that effect and seems to require enabling the Synaptics functionality beforehand: hw.psm.synaptics_support="1" I have no idea why one has quotes, the other hasn't. Additionally, it would be interesting if this causes a difference in console usage vs. X usage. I have the same problem with a Lenovo Thinkpad R61i, but as the console mode is "functionally dead", the problem persists within X. Accidentally touching the trackpad causes the mouse cursor to move whereas the only moving activity should be initiated by using the TrackPoint ("red nub").
