Adjusting the sensitivity isn't a driver issue. The driver reports that
values given by the hardware, and it's up to the userland input
processing to decide how these values are translated into cursor motion.
The exception to this would be if the max values the driver specifies
are inaccurate. If you will use input-events to determine the maximum
ABS_X/ABS_Y values the driver reports, I'll check to see if there's a
problem here. I've described how to get the ABS_X/ABS_Y in previous
comments, so I won't repeat it here.
