I've the same problem with a Lenovo Thinkpad Z61p and ATI M56GL
[Mobility FireGL V5200] on Ubuntu 12.04. I'm not able to use the
proprietary driver, because the support for this chipset was abandoned
years ago. So I've to use the radeon driver.
Here is some info:

So I've direct rendering:

direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
GL_NV_conditional_render, GL_AMD_draw_buffers_blend,

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
OpenGL version string: 2.1 Mesa 8.0.2
Not software rendered: no
Not blacklisted: yes
GLX fbconfig: yes
GLX texture from pixmap: yes
GL npot or rect textures: yes
GL vertex program: yes
GL fragment program: yes
GL vertex buffer object: yes
GL framebuffer object: yes
GL version is 1.4+: yes
Unity 3D supported: no
... so Unity 3D ist not supported
-----
With the workaround from Carl I replaced all installed Mesa-Packages with:
libgl1-mesa-dev 7.11-0ubuntu3.2
libgl1-mesa-dri 7.11-0ubuntu3.2
libgl1-mesa-glx 7.11-0ubuntu3.2
libglapi-mesa 7.11-0ubuntu3.2
libglu1-mesa 7.11-0ubuntu3.2
libglu1-mesa-dev 7.11-0ubuntu3.2
mesa-common-dev 7.11-0ubuntu3.2
mesa-utils 7.0.3~rc2-1ubuntu3
and configured the module in /etc/modprobe.d/radeon-kms.conf with:
options radeon modeset=0
With a worse result:
[ 19.912] (II) AIGLX: Screen 0 is not DRI2 capable
[ 19.912] drmOpenDevice: node name is /dev/dri/card0
[ 19.912] drmOpenDevice: open result is 12, (OK)

[ 19.912] drmOpenByBusid: drmGetBusid reports pci:0000:01:00.0
[ 20.422] (EE) AIGLX error: Calling driver entry point failed
[ 20.440] (EE) AIGLX: reverting to software rendering
[ 20.441] (EE) AIGLX error: swrast does not export required DRI extension
[ 20.441] (EE) GLX: could not load software renderer
[ 20.441] (II) GLX: no usable GL providers found for screen 0
I've no OpenGL at all.
