We currently don't emulate the I2C bus provided by CUDA.

The MOL source has the comment /* this reply is important on B&W G3 */ in
the CUDA_COMBINED_FORMAT_IIC case (differentiating it from the general 0x2
error case); any idea if that's relevant? (0x5 is an SRQ error? I guess it
would also be nice to add constants for all these magic numbers.)
