Hey Peter,
You have to edit the FrameRender() function in povray.cpp. Heres what I did
for POV-Ray XR, my experimental version of POV-Ray.

Look for the part where it traces the radiosity preview:

// Note that radiosity REQUIRES a mosaic preview prior to main scan
   if ( opts.Radiosity_Enabled && !opts.Radiosity_Preview_Done)
      Start_Tracing_Radiosity_Preview(opts.PreviewGridSize_Start,
opts.PreviewGridSize_End);

   else if((opts.Options & PREVIEW) && (opts.Options & DISPLAY))
      Start_Tracing_Mosaic_Preview(opts.PreviewGridSize_Start,
opts.PreviewGridSize_End);


Then you can add code to conditionally trace the full scene ( I added the
+PTO command line option and the if statement )


 // GJP Parallel radiosity - If we specified we want Pretrace Only (+PTO)
then DONT do regular tracing after the pretrace.

   if ( !opts.Do_Pretrace_Only ) // added by GJP
   {
      switch(opts.Tracing_Method) // this was already in povray.
      {
       case 2:
        Start_Adaptive_Tracing();
        break;
       case 1:
       default:
        Start_Non_Adaptive_Tracing();
      }
   } // GJP

   // We're done.
