I am far from knowledgable on XFree, but for a laptop a friend of mine wrote a calibration tool that had the same problems. The problem was 'solved' by writing the changes in XF86Config and restarting X.
An idea I heard here a week ago was to let the driver open a different file (a device or a special made file for the purpose) and check if it has been written to just like (for example) is done with the serial port. Its ugly; but if it works, you don't hear me complaining. When you find a good solution, please share it with us, I'm quite interrested.
