Thanks, your patch does indeed fix the problem,
I don't see the sysctls above though:

fk at TP51 ~ $sysctl hw.psm
hw.psm.tap_threshold: 25
hw.psm.tap_timeout: 125000
hw.psm.synaptics.directional_scrolls: 8000
hw.psm.synaptics.min_pressure: 16
hw.psm.synaptics.max_pressure: 220
hw.psm.synaptics.max_width: 10
hw.psm.synaptics.taphold_timeout: 200000
hw.psm.synaptics.low_speed_threshold: 15
hw.psm.synaptics.min_movement: 7
hw.psm.synaptics.squelch_level: 25
hw.psm.synaptics.high_speed_accel: 100
hw.psm.synaptics.queue_window: 10
hw.psm.synaptics.scroll_squelch_level: 25
