SGI and nVidia on Linux

Maximum PCarchive.org has a news blurb stating that SGI and nVidia are teaming up to release a Linux graphics standard. There are VERY few specifics except to say that it is based on OpenGL and that there is a "as-of-yet unnamed Linux system vendor" that will also be supporting this. This would be a leap in the right direction if there is ever to be wide-spread software support.
