When I saw that it required more than a 5m fix on my Lenovo I just accepted this as my new setup and committed to only using the trackpoint instead. Ironically, as a programmer the trackpoint has now become crucial to my setup (easier on the wrists/thumbs; faster), and made it a lot easier to go "all the way" with tiled windows managers. So the lack of decent trackpad support made me really consider other setups that now I realise work better for me. Obv, your mileage may vary
