It appears I've been proven wrong once again, and here's where I got 
confused.

I was under the impression that the Radiosity pretrace only created 
samples from objects that were on-screen.  Since ideally the pretrace 
will create all necessary samples and further sampling would be 
unnecessary, this would result in only having samples for onscreen objects.

Second, I never thought to bump up the count setting to 1600, as Gilles 
suggested.  I always assumed that 100-150 was enough, as further detail 
isn't noticable in many scenes.

Some quick tests I just did show that simply going with much higher 
settings than I had (in fact, before I would have called them insane :) 
) was sufficient.

I stand corrected ;)
