Sorry I misunderstood what you were asking. The answer is, not without recompiling the kernel. CONFIG_PHYSICAL_START has changed several times from 1.x, 2.4, 2.6+ to compensate for hardware comparability issues. There are probably other offsets that have changed as well. I suspect the best place to find the all-inclusive list of changes that are required prior to recompile would be on embeded device forums.
