It reports OpenGL 1.4, but most of 1.5 features seem to be supported.
The "2.8" driver is the 2D driver. But with Mesa 7.5 you should have OpenGL 2.1. You're probably looking at the glx version string?

Or possibly the G35 doesn't support 2.1? You should get something like this:
OpenGL version string: 2.1 Mesa 7.7-devel
OpenGL shading language version string: 1.20

At least on the G45 this is already the case. Doom 3, Prey, Quake 4 all work fine.
