When using proto=bare, only one input device appears to be detected by psmouse, and both trackpoint and touchpad operate through that device. On the other hand, this device isn't detected to be a touchpad, so the evdev Xorg driver is used instead of the synaptics driver. That's why tapping, and every other touchpad-specific feature does not work.
