What I did for the GMA500 is to use the GTT to do scrolling by rewriting the framebuffer GTT tables so they work as a circular buffer and doing a bit of alignment of buffers. The end result is faster than most accelerated 2D scrolls unsurprisingly. Even faster would be to map enough of the start of the object on the end of the range in repeat and just roll the frame buffer base. That would get it down to a couple of 32bit I/O writes..
