I was reading through the linux-input thread (as mentioned in the subject)
regarding trackpoint detection, and noticed that it bore an uncanny resemblence
to the issue I'm currently having with my Thinkpad Edge E220S. I'll summarize
the situation on my E220S here, which I believe to be more or less the same as
the situation on the X220:
 - Main device is a Synaptics touchpad/
 - Trackpoint exists as a passthrough device/
 - Trackpoint not detected until first resynchronization happens.
 - Loss of sync can be triggered by moving the (undetected) trackpoint/

I forgot to mention one more point:
 - Upon resync, the trackpoint gets detected as "PS/2 Generic Mouse".
