Nearly complete, missing kitchen_probe.hdr
(I found one at
http://www.cgadvertising.com/pages/free-materials/hdr-maps.php

)

It can be reproduced simply adding +KFI0 +KFF10 (here on linux, so not
platform specific)

Yet, have you read http://wiki.povray.org/content/HowTo:Use_radiosity ?

Radiosity is not reproducible (there is a lot of randomness in it), you
need to save & reload radiosity data if you want always the same result
(such as in animation).
