[Rumor] More confirmation; NVIDIA G92/G92b bad

On August 12 The Inquirer made the damning accusation that the famed G92 and G94 cores powering the 8800GS/GT/GTS and the 9600GT were faulty across the line. This was not the first time The Inquirer had made this claim, but it appeared that NVIDIA AIBs were slipping notes on napkins to corroborate.
The buzz was that four board partners had come forward to identify a burgeoning trend in the death of these very popular NVIDIA GPUs. The trend had apparently been identified relatively early, but the failure rate has been steadily and alarmingly climbing. While big green remained mum on the situation, TheInq went so far as to say that it was a deliberate cover-up to save face in light of looming disaster.
The crisis, if true, would join the brutal beating NVIDIA is taking with the G84 and G86 mobile chips. NVIDIA's initial and stubborn admission of fault with the mobile cores suggested that a shipment to HP was the lone ranger in an otherwise-healthy line. Dell, Lenovo and other first tier OEMs have since come out with word that HP was certainly not the only manufacturer to receive a bad shipment. NVIDIA's lack of disclosure for the mobile market tends suspicion regarding their honesty in the desktop's.
TheInq is back to say that, not only are the G84, G86, G92 and G94 are bad, but so are their 55nm counterparts. The Inquirer has cited an NVIDIA Product Change Notification which identifies that the package soldering has been switched from High Pb to Eutectic Solder.
The change is unusual because there is typically little reason to alter the surface mounting material. Meanwhile, the solder technique has been identified as the point of failure in the mobile arena. The PCN also notes that the "Planned Implementation Date" is for the end of July, with shipments of the newly-altered G92 components on August 17.
The PCN notes that the change in solder material is to protect "supply and robustness." The choice in words is curious as a change to the stem the tide of mass failure does indeed fall under the domain of an improvement in product robustness.

The supposition is that thermal cycling, not heat in and of itself, rather the repeated transition from cool to hot, will cause the solder/solder substrate to deteriorate. Those 170 video cards of yours, well, are the machines turned off at night (cooling)? How long have the cards been in use?
