If you have 2 ATI vgas on a CrossFire system you can run fglrx module as DRM( if you can pleace post here )

Great solution for me( on Gentoo )( others can read the wiki posted below ):
-emerge latest libdrm masked package;
-emerge latest mesa hard masked package;
-read this section only: http://dri.freedesktop.org/wiki/Buil...d4f5268396b2b4
-configure your xorg.conf properly( with "radeon" Device ).
-reboot your system;
-enjoy it:-D

I think ATI need to release its drivers as open source[/code].
