MMULib 68040.library does not seem to work but without sources it will be too time consuming task..

EDIT: what happens is that mmu.library or 68040.library does some kind of test read, which causes bus error (access violation) as expected, error handler does some MMU page reconfiguration and when handler exits, test read instruction restarts but it still causes bus error which probably shouldn't happen. (MMU table has been changed, bus error isn't exactly the same)
