But even still, compiling with -m68040 causes gcc to generate different code than compiling without it (so effectively with m68020). In cases I looked at the instructions used where still fine to run on either, so nothing specific to the 68040 was generated. But if anything ever was then again the ".chip 68k" would cause an error out. I guess there isn't much extra in the 68040... move16, anything else? I guess gcc will never generate that in practice, so it is not a problem.
The only 040 specific insn that gcc would generate are the fpu insns, but the kernel does not use any floating point.
