What I would do is track down the source of the address for these loads in the asm listing, and see if I can tell. That said, b/c you mentioned all other system regs are 0, it means that PC and STATUS remained in their reset state, which means that whatever loads you see, they probably were not reached in the program flow. But, again, I mentioned this is a long shot, so lets see if you can learn something from the disassembly.
