It will work. Laptops usually have the video BIOS embedded inside of the motherboard BIOS so you have to extract it first, edit the speeds, and re-embed the BIOS and flash it like you would a normal BIOS update for your laptop. I've done it on a 9650M GT.
Again, I am not suggesting this as a permanent fix. nkalkhof already ignored my warning.
