It is very simple: the only thing to do is to comment out the /1000 at 
the end of the SunPos() declaration in your scene file. You may want to 
add the radiosity code (below).

As radiosity I use:

   radiosity {
     pretrace_start 0.08
     pretrace_end   0.004
     count 50, 1000
     nearest_count 10, 5
     error_bound 1
     recursion_limit 2
     low_error_factor .3
     gray_threshold 0.0
     minimum_reuse 0.015
     maximum_reuse 0.1							
     brightness 1
     adc_bailout 0.01/2
     normal off
     media off
     always_sample off
     //max_sample 1.0
   }

Note that without the divisor, the sun sphere (when switched on) becomes 
invisible somehow.
