Why don't you test it? I always keep a special POV file called
"tester.pov" for these types of things.

To answer your question (I hope): The effects of radiosity can be seen
without the use of HDR or an HDR light probe. Also, you can use HDR
without radiosity. HDR backgrounds can affect a scene either by
reflecting off of reflective surfaces, showing through transparent
surfaces, or through indirect illumination (radiosity).

If you have a white background (not a light probe, just a background
statment set to rgb<1,1,1>), it will illuminate the scene if radiosity
is included in the global_settings block. If you add a light, then you
will see it bounce multiple times depending on the radiosity's
recursion_limit.

In short, you don't need to use HDR in order to use radiosity. Radiosity
alone will increase the realism of your scene.
