Isn't much changed, well that's a white lie.  The ambient is dropped to near
zero for the radiosity images but that's a well known fact (I just tend to
leave it non-zero though, very low).  And the lighting is changed somewhat
as well as the sphere (not sky_sphere) for the sky because of the drastic
differences when ambient is dropped.  In other words, ambient and diffuse
for the sky is .6, .6  in radiosity and .67, .33 without.
The radiosity itself is done like so:

#if (Use_MP & Rad = yes)
 ambient_light <.1,.05,.025>
 ini_option "+qr"
 radiosity {
pretrace_start .08
pretrace_end .01
         media off
         normal on
         count 100 // or 50 // may be too low
         nearest_count 5
         error_bound .321
         low_error_factor .321
         gray_threshold .2
         recursion_limit 2 // or 1
         minimum_reuse .0167
        // brightness 1.333
          }
#else
 ambient_light <1,1.025,1.05>*.75
#end
}

Hope that tells you what you were wanting to know.
