Ok, I've tried to do (1,2), I committed a tested working version, then tried
the harder (3,4) and committed that but commented out so as to not affect the
working test_mmu(), tested and the test_mmu() still works. Currently it goes
into an infinite loop because I have done *something* wrong, I don't know what
however, so can you take a look and point out whatever mistakes are obvious to
you but not to me please :)
