Hm ok, then it wont do false reports, but only based on the assumption that 
there is no SFP004 for cpu >= 68020.

The CPU might be inaccessible, but the SFP is not.

Also the cookie was explictly designed and documented that both FPUs might be 
reported.

And i would be still be interested in the answer wether that address generates 
a bus-error or not. The startup code for almost all Pure-C compiled programs 
will check that address too, and this is definetely done without checking the 
CPU type first.
