not debating your statement, but as vfp is only 32 bit, only the part on the left of the hyphen is important ;-))
Although I am pretty certain that vfp6 and higher cannot be made to run on an Intel 8086, guessing at least 80386 instruction set is neccessary, which would imply 80386SX as lower bound ;-)
