I have been testing the FPU emulation code on my 68030/56 with no FPU
and I have seen the kernel complain only once about some unimplemented
FPU instruction. I forgot the exact error message and don't have the
logs anymore.
However, once I see it again, I'll report it.

Thank you! As I said before, there are many 68k machines out there which
have enough CPU power and memory to run Linux, but they don't have an
FPU and it's not easily to be added due to lack of an FPU socket.
