If you have a 68030 hooked into your A500.  SetCPU achieves its ROM mapping
by way of the MMU.  ROM code can only live at the location is was linked for.

[1] You can't legally do that; A3000 ROM code is licensed only for that A3000.
[2] You can't physically do that without an MMU in the A500.
[3] You can't logically do that with the A3000 ROM image, its 3000-specific.
