This line is correct, I think. The datasheet says Set bit 1 of the Configure Control Register (Index: 02h) to "1" to exit the MB PnP mode. IT8705F_CONFIG_REG_CC is 0x02, and the 0x02 in the line above is correct because it sets bit 1 (not bit 0). I _think_ I got serial output with that Super I/O at some point, but I can't remember exactly, so maybe there's still something todo...
