NVIDIA RGB Bug+ Windows 8: Display.inf 'fix" not working...

So.... this sucks.

Is there a workaroud for this:

1. Everyone is aware the HDMIFullRGB fix for the messed up NVIDA drivers. One must edit the inf file to enable proper 0-255 support
2. In windwos 8, it sees this as bad code, and will not allow the install
3. Is there ANYWAY to fix the HDMI RGB colorspace issue under windwos 8?
