Earlier this week AMD launched the Radeon HD 6850 and Radeon HD 6870 graphics cards as their first next-generation offerings that belong to the "Northern Islands" family. A day later there was the Catalyst 10.10 Linux driver release from AMD that added support for these new "Barts" GPUs to their proprietary driver, but no open-source support has yet to be found.
We said there won't be Radeon HD 6000 support ready for the Linux 2.6.37 kernel (the kernel release that's beginning its development cycle right now) and that we're unlikely to see any kernel mode-setting support ready before the Linux 2.6.38 kernel even if things go well.
