With all due respect, with enough people not using Google Chrome I think we can reliably rule it out, and it would only further cloud the issue for users and Apple.
The first three times I had a BSOD, all I had running was Powerpoint when it happened. If I applied your logic, I would have deduced it was due to PPT (and I even made a post about it in some support forum, either this one or an Apple-friendly site). Turns out that was not the case as now I've had it happen when I'm not running PPT.
It's clearly an nVidia driver issue. Has been since apparently the developer builds. Apple should have enough to go by on that. Worst case scenario they should roll back to the last nVidia driver that Snow Leopard was using, as that one was apparently stable for most, if not all of us. That would be a great first step in order to bring back stability. They can monkey around with new driver builds behind the scenes and stop using us early adopters of what was supposed to be Final Rev software as beta testers.
EDIT: I've also had the longest uninterrupted up-time right now using gfxCardStatus forcing the Intel onboard graphics, and with others reporting similar results, I think it's nearly conclusive that it's the nVidia driver.
