I think an LC has no FPU.  You'd basically be facing three issues:
	1) the 68LC040 has no FPU.  If you take out the FP context
	 save and restore code in the kernel and used binaries compiled
	 with -msoft-float (or is it -f?), you might get by.
	2) Your accelerator may have on-board memory.  It probably uses
	 an extension in macOS to map that memory to logical 0, so it
	 looks like normal RAM.  MacBSD will not be compatible with this
	 because it does not know how to map that memory.  If it's just
	 a drop-in replacement board for the CPU, it would probably work
	 (barring cache issues), much like Mike's DayStar '030.
	3) The '040 code in the kernel has not been thoroughly tested.
