Hmm, I wonder if this is another case of synaptics/xserver scaling like in bug #327428 (which I posted a fix to natty for yesterday). Can you refer to that bug report and see if it illuminates what's going on with your case? That bug also shows several tools for collecting data on how exactly the touch events are getting captured and handled, which you could probably use to analyze your issue.
