Possibly. But that's not to say that changing the microcode couldn't
provide a fix for it (provided that the FP was implemented in microcode
;-) Anyway, the point is that this idea of programmable CPUs is nothing
new. It's just taken this long for the technology to trickle down to the
microprocessor implementation.
