Is that true for real 68040 CPUs? I thought "fpu0 at mainbus" refers to 
the coprocessor (68881, 68882) on 68020 and 68030 CPU boards. There is:

# CPU-related options.
options         FPSP
#options        FPU_EMULATE

I beleive I saw somewhere that FPSP meant the built-in FP unit in 68040 
CPUs, while the FPU_EMULATE is for 68LC040 CPUs. But as usual, I 
probably don't know what I'm talking about. ;-)
