Interesting-it's entirely possible that maybe the firmware on this trackpoint is
different from the previous ones (only mention this possibility since it looks
like at some point in time they switched over from using the legitimate IBM
trackpoint modules to getting other manufacturers to make them). I know the
sensitivity setting works on my laptop with PS/2 through RMI4 though.
Could you maybe enable rmi4 debugging by passing rmi_core.debug_flags=0xff when
you boot your machine and get me the dmesg output from that after you've tried
changing the sensitivity value? Not sure I could fix it, but it'd be interesting
to see what's happening on the ps/2 side here
