I've posted a patch for an improved intersection routine in p.b.p some
days ago  (<news:4003c00f.84804802@news.povray.org>) which should give
you a significant speed up.
It should be easy to integrate it into 3.1 (the posted patch is for
3.5) but I don't have the sources of 3.1 anymore. I could give you a
Windows 3.5 binary (which probably requires that you 1st install the
official version).
I could do a test render on my machine if you are willing to share the
current (or a comparable) version of your scene to get some timing
values for my version.
