Intel Driver Now Builds SNA Support By Default

The xf86-video-intel driver, the open-source X.Org driver for Intel's graphics processors on Linux, is now being built with Sandy Bridge New Acceleration (SNA acceleration) by default. This means of acceleration is generally much faster than the long-standing UXA mode for both old and new hardware.
