What radiosity settings are you using? Not having done animations myself 
I was looking for fast but non-blotchy radiosity settings for the 
spectral render thing and from what I've tried something like this

      pretrace_start  0.08
      pretrace_end    1/min(image_height,image_width)
      recursion_limit 1
      nearest_count 10
      always_sample off
      normal off

together with scene complexity dependent count and error_bound settings
gives astonishing fast good looking results.
