Mmap'ing /dev/mem ought to give you access to physical memory and is
probably the right way to do this. I can't think of any reason why it
shouldn't work on the SA-1100 offhand.

What version of modutils?

My best guess is that something is going wrong with the code that resolves
branches when the module is loaded.
