MiNT steals exception vectors, because exceptions are supposed to generate
signals rather than draw bombs. There are only two logical solutions:

1) softload FPU emulation after MiNT
2) add FPU emulation to MiNT itself.

Eventually, MiNT could try to detect, if TOS already installed an FPU
emulation, and "reinstall" it upon own initialization. Now question: does
TOS (Milan TOS) mark the installed FPU emulation somehow? Perhaps a _FPU
cookie value or what?

No information, no code, you know ;)
