Radiosity tend to dislike scenes with a lot of reflective and 
transparent objects.

If that's your case, it MAY be worth it doing a multi-pass render.
A pass without most of the reflection and with the transparent objects 
removed where you save the radiosity data.
Use higher quality radiosity settings.
Then, a second pass with all the reflections and transparent objects 
where you load the previously generated radiosity data. Use relaxed 
radiosity settings.
As I have no personal experience with that technique, I can't give you 
advice about the details.
