First of all, I would ask for clarification about this. I wouldn't be suprised if it was allowed since it was something that was never thought of before (such as the ruling last year that the programming port could be used as a general purpose serial port).

However, depending on how much you want to pulse that switch, you can use a servo to press a mechanical limit switch, or an electromagnet that turns on or off, activating reed switch, or a light that activates a optical switch.
