Um.. ok. Not the way around I'd use, certainly...

Err.. now I'm doubly confused. Initially I thought you'd need to
change the size part of reg somewhere, but your description above just
convinced me you didn't (because you were essentially just shifting a
4M map up into the high rather than low 4M of the 64M space). Now
