Did radiosity make such a drastic difference before MegaPOV?  Hmmm...

  Yes, I used a very high brightness setting for the images. Perhaps not
the most realistic result, but at least artistic.

  No, the render time increase was due to more accurate settings for that
image. At lower settings there were some visible artifacts.

there
: ambient used?

  Yes, I used a very high brightness. Perhaps not very realistic, but at
least artistic.

  Yes. It's faster, better and easier to use.

I can't deny that. :)   Did you check out the link?

In the second radiosity image, I notice some strange lighting where the
spotlight object touches the ceiling. IMO there shoudn't be such a bright spot
there. Any idea what's causing it? (I haven't looked at the source yet)

  Yes: I have unrealistically bright radiosity settings. It makes objects
glow light by themselves (or more precisely, they reflect more light than
they receive).
  What you are seeing is just the white spotlight cylinder reflecting light
form the lit part of the scene. As I said, it reflects more than it receives,
so that is what is causing the effect.

  Btw, if I use realistic brightness in this image (ie. brigthness 1),
everything is nearly as dark as in the non-radiosity image.

This is from cornell.pov in the 3.5 beta. It works for this
type of scene :)

global_settings{
  assumed_gamma 1.0
  radiosity{
    pretrace_start 0.04
    pretrace_end 0.01
    count 200
    recursion_limit 3
    nearest_count 10
    error_bound 0.5
  }
}
