One thing you can do to exagerate the effect of your photons:

Use a two pass render.

On the first pass, chank up your light by a factor of 5 to 50 our more, 
and use a plain white ground plane. Save your photons.

On the second pass, bring back your light to a normal level. Use your 
textured ground. Load the photons.

It won't be realistic, but the photons effect will get stronger, 
possibly MUCH stronger.
