glxinfo reports strings:
OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile OpenGL version string: 2.1 Mesa 7.11 OpenGL shading language version string: 1.20
This may be specific to either Intel or the Mesa version you're using. Does setting LIBGL_ALWAYS_SOFTWARE=1 make any difference? For me this renders correctly with both r600g and softpipe (although softpipe obviously isn't very fast) on a fairly recent Mesa version (7684808f9ce2da944be3ca9cc1ac4661d9b167fb).
