A first thought. Recall that the i386 and m68k families have different data  
architectures the most obvious is that they are opposite endian. What I have  
done is to define a separate arch for white(NSIP) and black(NEXT) thus it  
forces you to keep binary's separate. And thus I can avoid any problems with  
data incompatiablity's. The FAT binarys work fine it is just data that can be  
a problem.

I guess i should send the diffs to the PVM folks for inclusion in future  
releases. Let me know if you would like the changes i made. BTW I am  
currently running 3.3.6
