Try this:

#Set trackpoint sensitivity to highest.
if [ -f /sys/devices/platform/i8042/serio1/serio2/sensitivity ];then
         echo "Making trackpoint more sensitive..."
         sudo sh -c "echo -n 255 > 
/sys/devices/platform/i8042/serio1/serio2/sensitivity"   #Makes it a 
very light touch. Default: 128
         sudo sh -c "echo -n 255 > 
/sys/devices/platform/i8042/serio1/serio2/speed"         #Not much effect.
         sudo sh -c "echo -n 3 > 
/sys/devices/platform/i8042/serio1/serio2/inertia"         #Negative 
inertia. Default: 6
else
         echo "Cannot adjust trackpoint; 
/sys/devices/platform/i8042/serio1/serio2/sensitivity not found"
fi


(Note that the values of serioX/serioY are system-dependent).
