To continue in that vein:

CPU/support chips       required options
68020                   does not work
68020/6888[12]          does not work
68020/68851             FPU_EMULATE
68020/68851/6888[12]    nothing
68030                   FPU_EMULATE
68030/6888[12]          nothing
680LC040                FPU_EMULATE
68040                   FPSP
