Today AMD has officially released their low-end and mainstream graphics cards in the Radeon HD 2000 family, the Radeon HD 2400 and Radeon HD 2600 series respectively. While these new graphics cards should already be at your favorite retailer or presently in route, where are the Linux drivers? AMD's high-end Radeon HD 2900XT was pushed out the door in early May, but we have yet to see any official support for that or any of the graphics processors in the Radeon HD 2000 series under Linux.
