This will cause the I2C to start toggling SCL. I mention it here because I think the "free data format" mode is available on most processors. (The only device I know that does NOT support "free data format" is OMAP35x.) You might have a lot less processor-specific code with this approach and it would be applicable to more devices. I don't have any time to write the code/patch myself, but I thought I would at least toss the idea out there.
