Dispersion, per se, doesn't make you get a spectrum with photons. Most times
it just makes the refracted rays look yellowish. If you want to get a
spectrum you should specify a color_map inside a light_source block. This is
just what the spectrum macro included in the prism demo scene does. As I
said before, sometimes the spectrum seems to disappear. Just rerender it and
you should finally get it. No specific ini or global settings are needed
(but I may be wrong...).
