Default Re: [270.18] Overclocking is _still_ broken for 8xxx (probably 9xxx too) class GPUs

On my class of GPUs (8800GT to be precise) powermizer doesn't work not because it's broken or buggy, it's because these GPUs don't have power profiles at all.

I tried adding power profiles manually via editing BIOS with NiBiTor but that didn't have any effect so I reverted back to my original BIOS. I'm not an NVIDIA engineer and I have no idea who to ask how to properly enable power profiles. I tried copying the settings which I extracted from a 9800M BIOS but it seems like that wasn't enough. And, yes, I had adjusted 9800M clocks/voltages for my GPU anticipating your further questions and doubts.

Oh, and one more thing I forgot to mention - I need to reclock back my GPU when I want to use VDPAU. At 160MHz core 8800GT GPU doesn't have enough juice to decode even 720p H.264 streams - I get framedrops. At nominals speeds my GPU handles 1080p video clips without any problems.
