Added:
Pixel shader ------------------------
Programmable texture blending modes - Yes. EXT_texture_env_combine is
supported, and ARB_texture_env_combine
and ARB_texture_env_crossbar will be
soon. ATIX_texture_env_combine3 is not
supported, but probably could be.
NV_texture_env_combine4 is also not
supported, but I think the hardware
could do it. The extension is marked
as "Nvidia proprietary," but I have no
idea what their current stance is on
this WRT DRI (nor am I in any position
to ask them, obviously).

Projective Textures------------------ Yes, I think.
Changed:
Mapping
=======
Environment Bump --------------- No.
Dot Product 3 Bump-------------- Yes.
Emboss Bump -------------------- Yes. The card supports all the required
blend modes, but NV_textgen_emboss is not
supported, so you have to calculate the
texture coordinates yourself. This
extension is also marked as Nvidia
proprietary, so see my comment about
blending modes, above.

Texture
=======
Cache -------------------------- Automatically supported by the hardware.
