  No.
  Diffuse affects radiosity. That's why it's called "diffuse inter-reflection"
in the first place.

  And this is a good thing. You get a lot better results faster using real
light sources than using high-ambient objects. This is because real light
sources are very fast to calculate, while getting a good illumination from
a high-ambient object needs tons and tons of samples.
