Radeon driver is Slower than VESA ...

Recently i tried to run haiku with vesa to see how it performs. And I was moved how fast it was(After using with (buggy?)radeon driver most people would think that way). Here are some observations:
Running haiku with Radeon Driver (on Radeon Mobility X600):
- Supports native resolution.(1680x1050)
- Supports Video Overlay
- Redrawing is worse than VESA driver. Example: Resizing Terminal(or any) window causes flicker while using with Radeon driver, but while resizing with VESA driver it was really smooth(no flicker at all).
- Decreases system performance. Example: With Radeon driver, while playing audio or video every random(between 3 - 10) seconds there is noise/glitch in sound. But after testing with VESA the glitch/noise was gone.(Before testing with vesa,i thought that it was related to MediaPlayer or MediaServer changes, but it seems not the case). And performs a bit slower in normal usage.
So far VESA driver performs much better than radeon driver at redrawing smoothly (almost with no flickering) while resizing,moving, etc.
So there is a bug or a missing function(s) in radeon driver that affects system performance really bad. With VESA,I could able to see how much better Haiku become. But it eats too much CPU time, escpecially while playing videos.
