Pi Face detection currently works on checking if the SPI bus exists in /dev/. If it doesn't then the Pi Face doesn't exist, if it does then the Pi Face exists. Even if it isn't plugged in.
What should happen is that emulator should make a request to the Pi Face over the SPI bus requesting a version string from the microchip (MCP17S23). I can't find a data sheet on this though so I don't know what command to send.
