New Xorg-server is out for some time now. Mesa is preparing the release for the end of next week.
I'm going to package a late mesa git shot from its 9.0 branch to start packaging Xorg-server and do the required driver rebuilds. Once Mesa is final I will move them all to testing. Please don't touch Xorg related packages while I'm on it in staging repo.
Note: rebuilt driver will from now on depend on Xorg-server major ABI version numbers and no longer on the server release version number. This should make it more clear when rebuilds will be required.
