Think of them as a kind of a cluster in a box. Communication mechanisms like DIPC and networks then all collaps into shared memory and interrupts. A concept like that can even deal with processors running different operating systems like Amiga/68k + Linux/PPC. Memory bus congestion is probably going to be a serious problems since those card have not been designed with the memory bandwith to supply both cpus.
For above configuration I'd say ignore the '020. It just produces very serious congestion of the memory bus on the motherboard.
