The orion_nand module gets automatically loaded on platforms that
require it. The module (check with modinfo) has a module-alias
"platform:orion_nand". Now, there are some calls to
kirkwood_nand_init() in board-setup files under
arch/arm/mach-kirkwood/. You could try to figure out which file is
used by the DreamPlug and have it not call kirkwood_nand_init() for
the DreamPlug.

At least, that's what I would try first. Good luck!
