There are a number of utilities that will display the configuration of all pins - raspi-gpio is the one I use. My intention was to confirm that the I2C0 function was not multiply mapped, but you can do that yourself, and from what you say it probably isn't.

You are likely to get more answers on the Raspberry Pi forums.
