Often it helps, if you specify radeonhd, not radeon as driver in xorg.conf . I see this as a bug that radeon is by default preferred over radeonhd. There have been fights amongst the 2 drivers' maintainers on the x.org devel list. Fact is, that radeonhd works on more of the newer chipsets and better (including higher resolutions).
