Gotcha....

The i2c driver compiles on the Pi3 but I don't know if it works yet.  I
also have yet to check the GPIO outputs (the "led" driver does *not*
work and that might portend bad things, but we'll see.)  I'll get the
breadboard out with one of my spare i2c modules and see if I can talk to it.
