That's what I was thinking, that it's going to be a microcode patch. Another
less likely possibility is to trap the instruction to software as was once
proposed for the Pentium FDIV bug before Intel decided to recall the chip.
One more piece of information: It's not just Opterons. It's all AMD64 at
revision C0 and higher.
