As I said in p.u.patches, I had a problem using photons and area_lights...
In the megaPOV doc, it is said that area_light by default are considered 
as point light by photons. This was ok for me...BUT, I didn't managed to 
have photons with them until I added the area_light keyword in the 
photon part of the light source.

light_source {  // FDirect01
   <0, 0, 0>
   color rgb <1., 1., 1.>
   area_light
   <0, 0, 9.>, <0, 9., 0>,
   14, 14
   adaptive 2
   jitter
   orient
   matrix <0.5000001788, -0.866025269, 4.110460239e-008,
       -3.943076266e-008, 2.469813865e-008, 1.,
       0.866025269, 0.5000001788, 2.179896796e-008,
       130., 140., -6.119594218e-006>
   photons {
       refraction on
       reflection on
       area_light   // HERE !!! without this, no photons !!!
   }
}

Did I miss something ??
