Reproducible with swrast and i965 (GM45), gallium drivers seems fine. Just grab latest Firefox and go to http://playground.christianwannerstedt.com/projects/consumed/

    glsl: Initialize samplers to 0, propagate sampler values to the gl_program
    
    The spec requires that samplers be initialized to 0.  Since this
    differs from the 1-to-1 mapping of samplers to texture units assumed
    by ARB assembly shaders (and the gl_program structure), be sure to
    propagate this date from the gl_shader_program to the gl_program.
