I would like to understand more on how enabling PnP discovery for i8042
affects the touchpad. Do you see it using different interrupt or IO
ports? What protocol does the touchpad use with/without PnP? If the
protocol is the same, do you see difference in the ranges (pressure,
etc) reported by the device?

Thanks.
