Just a quick test with evtest and xev confirm that it's the USB keyboard device which also does the normal key presses this sending the CTRL, while the other "USB keyboard" is the actual touchpad which then sends the mouse wheel events. Which explains why your keyboard also stops working.
@Mark: Got a link to the patch(es) that improved the touchpad? Would make a start point for finding out how to disable this properly.
