OOC, what exactly is the ambient occlusion pass used for? After all, the 
global illumination effect should already be accounted for by the 
radiosity pass.

AFAIK, in shader-based render engines, AO is used to get self-shadowing 
right, and/or to /fake/ global illumination.

So I guess what you're doing there is actually just deepening the 
shadows for artistic effect, and might better be served by tone mapping.
