missing opengl extensions with nvidia-glx-new

I have enabled the restricted driver for my card using the user interface and it loads up fine. Most 3d applications work and at fast speeds as expected (eg: compiz works fine). But I'm still missing some crucial opengl extensions, and glxinfo reports Direct Rendering as no. Most of these extensions come back if I remove the nvidia driver.

Meaning some games dont work:
* Quake4 would say GL_ARB_texture_compression not found
* billard-gl will load but the text from the menu is unreadable and out of place (http://ubuntuforums.org/showthread.php?t=707594)

In contrast if i remove the nvidia driver, billard-gl would work fine, just slow (software rendering)

If i recall correctly, there should be some mesa extansions on the system in addition to those provided by the nvidia driver, I seem to be missing that at the moment.

Hardware:
NVIDIA GeForce 8800 GT 512 MB
2GB DDR2-800
Intel Core 2 Duo E6300
