Try shooting lots more photons on the first pass and making a severely 
bumpy micro-normal. This might blur the reflections enough to get good 
results. A little while ago I tried to do a similar trick using micro 
normals to simulate pathtracing with just a really bright ambient object as 
my light source. Never got anywhere... Nothing but black. But this looks 
like a good idea. Maybe someone needs to make a patch. I'd give it a try if 
I had the patience...
