Part of this might be resolved by better processing in pc532/pc532/trap.c.
I didn't do very much work on the fpe traps.  I just sent them to
signals.  It might be appropriate to look at the trap and see what caused
it and then make a decision as to what to do.  We (I? you? ???) should
look at what generates the FPE traps and then decide what the best
action to take based on what caused the FPE trap.
