All these capabilities are in ROM.  The finder uses them.  Segment loader,
process manager, all that's in ROM.  You would still have use of them even
if the finder wasn't there.  The finder's simply a glorified app.

Also, there is a ROM call to switch MMU modes.   Have a peek in IM V -- OS
Utils:

PROCEDURE SwapMMUMode (VAR Mode:  Byte);
CONST false32b = 0; {24 bit}
      true32b = 1; {32 bit}

Will that solve the mapping problem??
