When using the shield, the GPIO pin numbers are different. This changes the pin number for the vibration motor to one that is an output for the shield.
When looking at the shield with the outputs towards you, the vibration motor should be connected at the second from the left position (I just started from the left and put the lights on the first one).
This is a pretty ugly hack and we should figure out a better way of configuring which pin is used.
