Textures in AGP memory is currently not allowed, but they are disabled in the Mesa driver as well, for some reason. If they are allowed in the future, Texture address checks probably have to be implemented but that should be a minor task.
I certainly turned them off because they were crashing my box in the original "hey it sort of works" codebase. I don't know if its that or if someone did more work on it later.
I managed to get AGP textures working after some extra return-value checking. At least it seems rather stable, so I implemented a texture address check in the verifier, which checks that the texture is actually fetched from a client-drm-mapped memory region. System memory textures are still rejected.
So unless someone has anything against this, I'll check it in in the via drm driver, and put up a modified unichrome_dri.so on the unichrome site for some serious beta-testing. Possibly also with different user command buffer sizes.

Great Thomas,
Where is the source/patches for the DRM/3D driver? I will update my Fedora RPMS and try it out ...
Cheers
