Yeah, we've got some Dy-4 m68k-based single board computers that allow the lower 3 bytes of the MAC address to be programmed. It's kind of annoying though, because the lower 3 bytes are always set to 0 and we have to uniquely set them for each board that we deliver to our customer. The MAC addresses were meant to be unique; why do you want the ability to change them? So you can make M$ viruses without anyone figuring it out who made them ;-)?
