Well, what I usually do when using the two-pass method, is to use a
lower error_bound on the first pass, and double or quadruple (always 2
with an exponent attached) the error_bound on the loading pass. What
this does is average more of the samples together, in effect smoothening
the radiosity results somewhat. Of course this leads to loss of details,
but detailed errors are smoothened away as well. You could have a look
at my website as well, I've experimented a little with radiosity some
time back:

Hope that helps, even if just a little.
