That's the key. I'm not too sure POVRay's radiosity gives an unbiased 
result even with all settings turned up to the best quality. If there is 
just one reflective surface in the mix I'm downright sure it does not...

Even throwing photons in I believe there are situations POV will not 
handle correctly. Can we do a wall lighting one side of a room because 
it is itself lit by a light reflecting in a mirror?

Yeah, I should try myself :-)
