I think that you're right, they do seem to be waiting on nVidia. In fact, if you have access to 64-bit Windows 7 (I do through my school), the 195 beta drivers work for the 8800M, though SLI is still disabled (only one of my GPUs is properly used), and the temperatures tend to be a little high.
It's really a pain in the ass that we just have to sit on our hands and wait for nVidia to release something that works for us, but I have a feeling that we're going to be seeing what we need soon.
