updated pre-NV10 card init code for a small 3D rendering speed increase on TNT2 and TNT2-M64 cardtypes: gain is some 1-4% depending on colorspace and exact card-type. This completes the 2D driver's 3D related init programming sweep. Next up should be adding cardID's and adding a new nv.setting to force screen aspect. Bumped version to 0.77.
