The non-empty PT_NOTE is currently nested inside the first PT_LOAD segment, if I'm not mistaken? I think it needs to have a companion section that can be assigned to it, to force the offset to be not within the other PT_LOADs.

Not quite what I meant (I wanted a segment with 0 virtual address, and a different segment with zero file size). That being said, I actually don't think we need a 0 virtual address case, having given it a bit more thought, since there's nothing special about this case.
