I can confirm this breakage on debian when upgrading
xorg-xserver_1.6.1.901-2 to xorg-xserver_1.6.1.901-3. See the
differences between
http://ftp.de.debian.org/debian/pool/main/x/xorg-server/xorg-server_1.6.1.901-2.diff.gz
and http://ftp.de.debian.org/debian/pool/main/x/xorg-server/xorg-server_1.6.1.901-3.diff.gz
related to dri2!
