I'm not sure what you're talking about... There was no such restriction on 
pre-1.3 NetBSD/Amiga.

The only thing which has changed, is that NetBSD/Amiga has now (partial) 
support for FPU-less machines. FPU machines have been fully supported from 
day one.

The only use of -fsoft-float I know of, is when compiling the kernel. The
kernel itself doesn't issue FP operations (other than, to save, switch and
restore floating point context on behalf of user processes).
