We are talking about the installer, which runs on MacOS. The mac68k
GENERIC kernel includes the FPU_EMULATE option, which does FPU emulation.
So it should (or at least might) work. Of course SoftPFU might fool the
kernel, since i will change trap vectors etc. But after install, you can
boot without SoftFPU.

Still all speculation, though. I don't have a FPU-less Mac to try.
