If you look at the m68k machine description then you will see that the only 
difference between 68020/68030/68040/68060 is gcc avoids slow floating-point 
instructions on the 68040 and 68060 which are implemented as software traps.

Please explain why the kernel should be optimized for fast floating-point 
computations.
