In my experience problems which appear random usually aren\'t, but rather have complex dependencies. It seems to me (as a non-owner of a 5DII) that you need to approach the problem systematically. Find a situation which demonstrates the problem, then systematically change everything on the camera (metering mode, AF mode, ISO, noise reduction, everything..) and see what happens. If that yields no results, you can assume that the RF interference is not to blame and start looking at elements of the picture (colour hue, clipped colour channels, type of lighting, etc). Perhaps temperature is a contributing factor too.
Alternatively hunt through images which show the problem and try to find similarities - a sort of data mining exercise.
Given how long this has been a topic of discussion, and the fact that Brainiac has been looking at it a fair bit, i can\'t help feeling that anything less than a completely rigorous (and time-consuming) approach will give the answer. Think of it like playing CSI, but with real scientific method
