I have a Radeon X800 GTO (R480) and I had problems with Gnome 3, namely
it would not run in standard mode,
For that I had to enable modsetting on the kernel.
Device Drivers --->
Graphics support --->
Direct Rendering Manager (XFree86 4.1.0 and higher DRI support) --->
[*] Enable modesetting on radeon by default - NEW DRIVER
Hope this helps,
Clemente

Fellow Gentooers,
although I am very happy running a Gentoo box, sometimes I bump into some
difficulties, esp. when updating packages. This time I am having a hard
time reconfiguring my video card, which was fine but is not anymore after
the last system update I've made. Gnome session goes up as usual but the
resolution is not fine and monitor complains about not being in the
recommended mode.
My video driver is an ATI Radeon 9600 (RV350) and somebody has already
updated the section on the Gentoo wiki
http://en.gentoo-wiki.com/wiki/Radeon#Kernels_.3E.3D3.0.0 informing that
there might be incompatibilities concerning the RV350 firmware. I just
don't have enough understanding of the video related parts of the system to
tweak and fix this issue. How should I proceed when I have a problem of
this sort?
How do I know what is the video backend in my system? Is Xorg the only one
possible? What can I do to fix this problem?
The link you provided says that you should disable framebuffer in your kernel
config. Have you tried that?
