Is your dirt a layered texture? I think there's a separate max_trace_level
setting in the radiosity block which would need to be the same as the
global one. I haven't tried this, though, so I could be wrong...

This would also explain why transparent objects seem to block radiosity
for some people (there was a post to this effect recently).

Specular and phong highlights are calculated from light sources alone, I
think. If you removed the light sources and lit the scene using only
radiosity then this is to be expected.

I did notice the granularity in your original image, but I wasn't sure if it
was the desired effect or not!
