Radeon video artifacts

I own a laptop with a ATI Mobility Radeon 9700, and since the first time I used the open-source driver (xf86-video-ati) the video quality sucks......
The image isn't full of artifacts, but shows them when there is a transition to black or when the color is really dark. Let's show an example.

I must say this problem comes from a long time ago, when I first used Ubuntu a year ago, then with Gentoo and now with Arch. I've posted in the forums of the first two, but no one answered so far.
I must also say that this problem disappear when a use the fglrx driver (in all the distro I used so far). I just don't want to the the proprietary drivers because I want a good AIGLX support, and since I saw those wonderful news about ATI releasing documentation about r300 chipsets I've been like "SWEAT!!!".
I've googled for this problem and so far haven't found anyone with a similar one. I've tried several version of the driver (6.6.*, 6.7.*, 6.8.* and git) with no luck, using the 6.8.0 version now. I just don't know what to do now, and I'm begging (literally) for someone's help. Hope I'll find in this forum

Edit: I don't think the problem comes from the driver, but from Xorg configuration, because I've just tried the vesa driver and I had the same problem.

Here's my xorg.conf file
