I heard somewhere that mainframes are not particular good at floating point
stuff and if I remember correctly the IBM one's are only IEEE (floating
point standard(can't remember the number)) compitable since a few
generation (S/390 G3 or G4?).

I tried to run 3.1 in 64 bits sometime ago on IBM Power machines. no speed
difference. And I never tried to let pov use more then 4 gigs of memory
either.

Also there are two bugs at least in 64 bit versions of pov 3.1: The time at
the end of the render is negative  and radiosity does not work at all. I
tried to report it as a bug, but the Pov-team wasn't interested.

I haven't tried to get 64 bit compile with 3.5, haven't even managed to get
a 32 bit version on AIX (but that has more to do with me than with pov ;)
