The code does not try to detect which FPU is installed in the SFP, it only 
detects its presence. I think that's not possible. And the current detection 
works for all cases except when you have both 68020+6888x and SFP. which seems 
to be quite rare ;) At least software would prefer to use the real 68881 then 
anyway, so it would just be a matter for informational purposes.

But i still would like to know wether those addresses generate a bus-error on 
the falcon ;)
