There is one difference that Lispworks found between the two CPU
generations.  With the addition of the second FPU, a few of the
floating point instructions had a bit field that was no longer "don't
care". In the case of LispWorks, this was fixed the day it was
discovered, and all subsequent distributions will run on either CPU.
