It might be that you have to pass in an extra value into those
float -> int conversion routines, which describes what to do if the
conversion is going to overflow.  That's because the behaviour is
different depending on the guest architecture.  x86/amd64 always
give 0x8000...., whereas ppc gives either 0x8000... or 0x7FFF....
depending on the sign of the argument (IIRC).
