yup. good work. i'll check it again, but iirc, it gives accelerants for 2D features (bitblt, fills, etc), no 3D stuff ...
That's still very valuable source of information and certainly more readable than X sources ...

For 3D Acceleration, there are docs available for the Voodoo cards,

The docs archived here for Voodoo2 seem to say how all the card registers are mapped in memory but it is missing the crucial "triangle command" section.

yes, the once-famous "GLide" interface of 3Dfx early chips was one of the rare one to have documentation. Unfortunately, there's not much glide-based cards sold nowadays ...
Actually, i was thinking of using something similar to SANiK's vm86 translator to translate linux NV driver ... Parse code, identify things that are linux-specific and replace them by $(YourOS)-specific...
The i470 of Intel (some embedded 3D chip) also has very open description and the doc is cached at the same website as above.
