Nouveau, the upcoming open-source NVIDIA display drivers for Linux, has been merged into the mainline DRM and Mesa git trees. However, this project still isn't ready for prime-time yet as more work is still left to be accomplished. The reason for this code merger is to make it easier to develop in the trees. More information and discussion can be found here.
Nouveau, the free open-source NVIDIA driver project, has published a status update for this project. More information can be gathered here.
David Nielsen has started a pledge drive for the Nouveau Driver Project. He is attempting to raise money to further develop these drivers, which would allow for open-source 3D acceleration on NVIDIA hardware. At this point nothing with these open-source drivers work, so users wanting 3D acceleration are required to use the closed-source NVIDIA drivers. David Nielsen said he will donate at least $10 USD to the project if 1,000 other people do the same (for a total of $10,000). At the time this news story was published 91 people had promised to do so. You can read more about this pledge here.
