>Description:

Latest pms synaptics touchpad changes make my touchpad unusable, every
finger move is interpreted as a mouse wheel change.

My sysctl values are:

hw.synaptics.up_down_emulation = 2
hw.synaptics.up_down_motion_delta = 1
hw.synaptics.gesture_move = 200
hw.synaptics.gesture_length = 20
hw.synaptics.edge_left = 1632
hw.synaptics.edge_right = 5312
hw.synaptics.edge_top = 4288
hw.synaptics.edge_bottom = 1568
hw.synaptics.edge_motion_delta = 32
hw.synaptics.finger_high = 35
hw.synaptics.finger_low = 20
hw.synaptics.two_fingers_emulation = 0
hw.synaptics.scale_x = 16
hw.synaptics.scale_y = 16
hw.synaptics.scale_z = 1
hw.synaptics.max_speed_x = 32
hw.synaptics.max_speed_y = 32
hw.synaptics.max_speed_z = 2
hw.synaptics.movement_threshold = 4
hw.synaptics.movement_enable = 1
hw.synaptics.button_boundary = 2288
hw.synaptics.button2_edge = 2858
hw.synaptics.button3_edge = 4085
hw.synaptics.finger_scroll-min = 5
hw.synaptics.finger_scroll-max = 12
hw.synaptics.finger_scroll-hysteresis = 30


And dmesg:

pckbc1: using irq 1 for kbd slot
wskbd0 at pckbd0: console keyboard
