It makes a huge difference, with the acceleration patch:
commit b1ee26bab14886350ba12a5c10cbc0696ac679bf Author: Benjamin Herrenschmidt <benh@kernel.crashing.org> Date: Wed Oct 15 22:03:46 2008 -0700
radeonfb: accelerate imageblit and other improvements
reverted, the test case takes 25 seconds or more instead of the 7 or 8 seconds we're seeing now.
