[arch-dev-public] Xorg-server 1.6.0 moves to extra

Xorg-server 1.6.0 and its related drivers will make their move to extra. This new release features input device properties, DRI2 and kernel modesetting (KMS). Note that DRI2 and KMS are only implemented by the Intel driver at this moment. This release also comes with a new driver: xf86-video-intel-legacy. This driver is an old intel driver version, patched to support recent xorg-server versions. This driver should be used by people having problems with the newer xf86-video-intel driver. People still using xorg-server 1.4.2 are advised to upgrade and replace intel or i810 drivers with the legacy driver.
