Huh? You should be dealing with segments and not sections (as you are
loading and not linking the image) and then only LOADable ones. I believe
there is no segment mapped at zero for the current kernel. If a segment
has a null load address then it still have to be loaded -- you may
consider placing part of it away for the time being or just relocating the
loader.

There are only two LOADable segments, at 0x80040000 and at 0x802b6000.
None is at zero. ;-)
If in doubt, just see how I'm loading ELF images in mopd. Or ask me a
question.
