If I understand you correctly, then you want the polygons to be rendered 
with radiosity illumination (honoring the effects of the spheres on 
this), but the spheres to be rendered with classic illumination (i.e. 
just the constant "ambient" term).

This is currently not possible. (However, if you're only interested in 
the spheres' radiosity effects on the polygons, and don't actually need 
the spheres in the image otherwise, then you can specify "no_image" on 
the spheres to not waste computation time on them.)

If, on the other hand, I'm misunderstanding you, and what you really 
want is everything to be rendered with radiosity illumination, but not 
honoring the effects of the spheres on this, then you can achieve this 
by specifying "no_radiosity" for the spheres; this makes them 
"invisible" to radiosity computations on other objects.
