However it is still not clear to me what coordinates are being reported by the device? You say that it always reports finger with smaller Y in SGM packet, but what about X coordinate? Could it be that the most benefit from your patch is because it reports proper slot from 2->1 finger transitions? BTW, you seem to have butchered single-touch protocol reporting for your device.
