I've just run the source you posted through the current code, which has had a
number of fixes put into it since beta.9 was released, and it now renders
identically to version 3.6 ... the radiosity really needed fixing before we
released beta 9 but I didn't want to let the old one expire without a new
beta being released.
I'll post a beta 9a shortly with the fixed radiosity.
