Oh I see. marcheu told me that this branch is dead, so I didn't bother 
to check it out.

I tried the i915tex_branch of mesa but it won't work for me. I can't get 
the X server up with the drm and i915 module loaded.
Multiple errors:
[drm:drm_user_object_ref] *ERROR* Could not find user object to reference.
After that the display is dead and the only thing that revives it 
somehow is vbetool post.

Thanks for the info. I think I go back to regular mesa 7.0.2 and check 
gallium again in a few weeks.
