The Radeon HD 2000 series hardware and later no longer has a dedicated blitter unit, so the 3D engine is being used here as well for this task. This ATI R600/700 blit support is yet another feature for Mesa 7.8, which should be released by the end of March. This proper blitter support should result in performance improvements for both 2D and 3D acceleration.
