The touchpad is working fine (including the dedicated buttons), but the trackstick doesn't work anymore. I suspect this is because it is detected incorrectly as an "AlpsPS/2 ALPS DualPoint Stick" when it should be (and previously was detected as) an "TPPS/2 IBM TrackPoint" (checked with other S440 owner). A friend replaced his T440 touchpad with a T450 touchpad from synaptics, and his trackpoint is working fine.
