Suppose you are trying to do a virtual 68020 on the 68020.
How do you deal with attempts by the virtual 68020 to
return from a bus error?

There are a lot of things in the bus error stack frame that
are reserved and/or undefined.  If it has changed some of those,
it seems that it could really screw over the system when
you load them. 

Is there some way one can validate such a stack frame to make
sure that it won't do anything funny when used?
