This makes the (probably invalid?) asumption that all of the other
PMMU using drivers (ab040, etc.) are preserving all the previous
PMMU mappings - otherwise, bang goes the MP and VM, and you'd be
pretty lucky not to get a crash. 

I think that these drivers come into the category of "must run before 
MiNT" (if they dont preserve all previous PMMU mappings).

as far as I can see, this is the only way of safe way of handling this.
