Ok, thanks for testing!

Now that could mean two things ... either the Falcon custom chip that
is responsible for dispatching the memory accesses (the Combel chip, I
think) still takes care of that supervisor logic ... or the low memory
is now protected via the MMU.

I guess we need to decode the MMU tables of TOS to find out...
