• Implement m68k_read_disassembler_* properly
  
  The previous implementations of m68k_read_disassembler are unsuitable due to
  interactions with the memory mapper. A read from memory by the DASM should not
  mutate system state.
  
  So we modify the m68k_read_disassembler_{8,16,32} functions to do the memory
  mapping themselves without causing page faults (bus error exception) or
  updating the page flag bits (which could really upset the kernel).
  
  Now all we need is a debugger/disassembler...
