Re: The question I've got is...

You may prefer it, but it seems pretty obvious from the 5D Mark II issues fixed in firmware that Canon is processing the RAW data before saving the RAW file in camera.

It doesn't seem unreasonable to me that they would do some camera/sensor specific corrections such as balancing the green channels before saving the data. I'm mixed on correcting out the pattern noise when the info is including in the edges outside the imaging area of the RAW file, but right now it seems the firmware is doing something incorrectly since the pattern is exhibited in the imaging area versus the blacked out edge.
