Code before looked only at bit 31 to decide if a port is unused. However dcb 4.1 spec says 0x1F in bits 31-27 and 26-22 means unused.

Having scanned a large number of bioses, I'm pretty convinced that the appropriate i2c bus is always number 2 in the list on <g80 - I'm not sure about later cards yet. There's still a lot
