If you recall, two years or so ago, ATI could not pass muster, but in the end, it turned out to be delays and a whole lot of behind the scenes arm twisting. This time however, it is worse for the green team, it looks like it won't get compliance without a time machine and a lot of soldering.
This time, the problem is plain and simple incompatibility, we have reports of 8800s not working in several PCIe 8x slots. While I was not able to test this personally, several people I trust have reported problems. You can also see more here and here (P27 on this review). Several readers have reported similar problems to me as well, all involving no boot/recognition.
Toss in that the PCIe SIG compatibility list shows no sign of an 8800 anywhere and you have a problem. People familiar with the verification process tell me that there were more than enough plugfests for NV to get certification, but they either didn't try or failed. Judging from the massive compatibility problems reported to me, I would put my money on failure.
If you are buying one of these non-spec cards, be very careful that it works with your mobo, it is a minefield of hit or miss right now. Also be aware that if Nvidia ever gets SLI to work, your system may cease to function if you add a second card as per the BFG/OC link above. I think NV has a big problem on its hands. µ
