APUS_PROGRESS only makes sense when the MMU is off, which means all addresses
are physical, like in AmigaOS. So it's 0xeff01234 . AFAIR when the MMU is
turned on, things should be more or less set up for dmesg debugging to work.


BTW Alan, what about committing your code now so others can join your
experiments?
