Linux "Now that the kernel mode-setting page-flipping for the ATI Radeon DRM kernel module has been merged into the Linux 2.6.38 kernel and the respective bits have been set in the xf86-video-ati DDX, we're in the process of running new open-source ATI graphics benchmarks under Linux. Our initial results (included in this article) show these latest improvements to cause some major performance boosts for the open-source ATI driver as it nears the level of performance of the proprietary Catalyst driver."

"won't ever run KMS or kernel memory management (because the kernel guys won't accept driver code which is only a part of a driver), and hence will never be able to run Wayland or rootless X.


This story that proprietary drivers won't work with Wayland is incorrect. It won't CURRENTLY work, but the Wayland devs have already stated that it would be simple to add another backend which could call into the proprietary drivers. The KMS interface in Wayland could easily be extended by NVidia and AMD, just as they are already extending parts of X now.
"

KMS and kernel memory management are dependencies for Wayland support. The kernel developers will not accept KMS and kernel memory management pieces if the rest of a graphics driver is a binary blob. Wayland might be a different matter, but as it stands the graphics driver binary blobs will never be part of the kernel.
