Rudimentary AUX multiplexing support was added to kernel to make possible touchpad initialization on some HP EliteBook laptops with trackpoint. Disable multiplexer probing on all Lenovo laptops now as they use touchpad pass-through port rather than AUX multiplexer to connect trackpoint and at least two model (X120e and X121e) is known for getting PS/2 AUX port dysfunctional after switching back to hidden multiplexing mode. AUX MUX probing can be reenabled with setting of hw.psm.mux_disabled load= er tunable to 0.
