FDIV was really not technically a serious errata in the grand scheme of erratas. The Phenom TLB bug was worse. Intel basically denied/sat on the issue for half a year, stopped just short of slandering Dr. Nicely, etc, they made it into a complete PR disaster. If they came out the week after it was reported and just said, here's a workaround, here's an opt-in replacement program (which they finally did, but then it was too late), you would probably never have heard about the FDIV bug -- like the countless other errata we have software workarounds for.
