I have a vague recollection from my days of working on 405 that there
may have been something funky with FP emulation on there: e.g. FP
instructions causing 0x700 program interrupts instead of FP unavailble
interrupts or something.
I might be remembering incorrectly - the manual does seem to imply
that 0x800 FP unavailable is there as normal, but it might be worth
double checking this (against real hardware, if possible).
