So, I'd have to say there is no good advice on how to proceed in this situation. Simply because it's not just hardware that needs to change. The software, from the first stage boot loader all the way into the Linux kernel and rootfs may have to be modified. Not to mention that it would be hard enough to completely remove these peripherals on software, but making them modular in a way that they will work when they're not connect, *OR* connected . . . that will require a lot of work, I think.
Well, technically, I think that probably the best advice anyone could give in this situation. Would be to just leave the hardware in place, and simply disable the hardware through their drivers, somehow. Which may require recompiling the kernel, without the needed drivers, for these peripherals, on the board that do not need that specific functionality. Then put the darned thing in a box, and no one will be the wiser.
