And you have an hybrid graphics system where the 3D acceleration is not performed by the powerful ATI card, but the weak integrated Intel graphics...
The thing is that gnome does it own blacklisting, for example, the software rendering is only used when you force it, even if llvmpipe (the renderer) is installed, because gnome-session blacklists it.
And something similar could happen with your card.
Once again let's use some logic. You have two graphics cards, one weak (Intel integrated) and one strong (ATI Radeon).
If Gnome-session has to choose wich card to use, what would be?
I bet my *** that it would prefer the ATI, because it's a really powerful graphics card, not the weak integrated Intel graphics.
So the next thing to try is blacklisting Intel integrated graphics and de-blacklist ATI.
By the way, are you using xorg-edgers drivers?
Did you try, instead of xorg-edgers, this? (be careful to purge xorg-edgers before).
If you want to try those other drivers, there are a couple of flags you can use to force your system to always use the strong ATI card.
