FWIW, I've thrown together some patches for i965 which make gl_BaseVertex available as a system value, which I think is the right thing to do. I've tested the indirect draw case, and it seems to work fine. basevertex-v5 of my tree. It needs cleaning up and testing, but the hard part is in place. It mostly reuses Ian's existing GLSL IR lowering pass, too. --Ken
