	Certain revisions of the LC040 have a hardware bug that IIRC
	causes the conents of the some registers to be garbled upon an
	FPU trap - this makes it impossible to handle FPU code on such
	a CPU (unless you start emulating all instructions or something
	equally elaborate/deranged)

	They would require an m68k-nofpu distribution. The others LC040s
	would just benefit from one :)
