This isn't really a problem with powerd. As far as I know there's no standard interface (and likely as not no interface at all) for telling an input driver to stop sending events other than closing the input device, and powerd can't close the device on behalf of another process. The input stack needs to close the input device (preferably, or else stop listening to events from the touchscreen input device) whenever the screen is off.
