not without hacking the source but if I look at your touchpad output: the
problem is that the axis ranges are very different to what the touchpad
actually sends so the edge zones would be significantly larger. I suggest you
calculate the resolution and put theudev rule in place (locate a 60-evdev.hwdb
file and follow the instructions there). I'm a bit surprised though: we already
have a hwdb entry for the x220 and that should apply. maybe get your distro to
backport it.
