Xorg-server 1.5RC6 (18.104.22.1686) enters tesing. This version of xorg-server includes input hotplugging using hal, better EXA support and less memory usage. Note that this version requires an upgrade of all videodrivers. All videodrivers shipped with X.Org have been rebuilt to reflect this change. Nvidia drivers don't seem to need a rebuild, while AMD's catalyst drivers don't support the new X.Org version. Fglrx users should not upgrade to this version.
Please give this version of X.Org an extensive test run and report bugs.
