ati - How come my 11.10 3D does not work even though my graphics card is supported?

OpenGL vendor string: X.Org R300 Project

OpenGL renderer string: Gallium 0.4 on ATI RS690

OpenGL version string: 1.4 (2.1 Mesa 7.11)

Not software rendered: yes

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: no

GL framebuffer object: yes

GL version is 1.4+: yes

Unity 3D supported: no

---

So Unity 3D is not supported because of... "GL vertex buffer"? Am I understanding that right?

Even though I've been with Ubuntu since 8.10, I'm still quite the n00b, so any help would be great! THANKS!
