ati solved some problems and released a new hopefully better version...
this is not a simple bump as no amd64 drivers for this release are available
Has this update fixed the binary incompatibility with the latest xorg-server? The ati page still says xorg 6.8.2 as latest supported version.
http://www.phoronix.com/scan.php?page=article&item=501&num=1 says that max version supported is 7.0, will have to wait for 7.1 support
Already in portage.
