(From Phoronix News)

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.
