drm/nouveau/fb/ramnv50: Script changes for G94 and up
10053c is not even read on some cards, and I have no idea exactly what the criteria are. Likely NVIDIA pre-scans the VBIOS and in their driver disables all features that are never used. The practical effect should be the same as this implementation though.
