Savage2 is a free to play (but not opensource) game with native Linux clients,
it renders correctly with llvmpipe and fglrx.
It doesn't render correctly with r600c and r600g. Using latest git version
(commit 063c6b8f74d114241f663ef8fd93732a0a07c10f).

llvmpipe that works (sort of, its very very slow):
$ LD_LIBRARY_PATH=$HOME/mesa/lib/gallium glxinfo | grep OpenGL
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe
OpenGL version string: 2.1 Mesa 7.10-devel
OpenGL shading language version string: 1.20
OpenGL extensions:

r600c has part of the screen black (see attached screenshot
r600c_bad_partblack.jpg), but the menu is good (r600c_menu_good.jpg):
$ glxinfo|grep OpenGL
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RV730 9498) 20090101  TCL DRI2
OpenGL version string: 2.1 Mesa 7.10-devel
OpenGL shading language version string: 1.20
OpenGL extensions:

r600g doesn't have the blackness bug, but the main character is missing/totally
transparent you just see some swords running around
(r600g_bad_transp_lines.jpg),
and it has some thin black horizontal lines all over the screen. The menu also
has the thin black horizontal lines (r600g_bad_menu_lines.jpg).
LIBGL_DRIVERS_PATH=$HOME/mesa/lib/gallium glxinfo|grep OpenGL
OpenGL vendor string: X.Org
OpenGL renderer string: Gallium 0.4 on AMD RV730
OpenGL version string: 2.1 Mesa 7.10-devel
OpenGL shading language version string: 1.20
OpenGL extensions:

The video card is:
