Maybe we could design a new kind of extension driver (.x??), which could
be allowed to register to some m68k exceptions traps. This way, you have a
"driver" that registers for trap #2. An AES library then registers as a
"server" for it, and AES applications registers as "clients". I was
thinking about something like that to easily change the FPU emulation
(pure software for 020/030 only, full 68881 software emulation, missing
instructions for 040/060), or a new MMU manager for bus error handler,
etc...
