udev is not creating /dev/dri/card0 when radeon.ko is loaded by Xorg. Because of this dri is disabled when Xorg tries to open /dev/dri/card* and fails. Reproducible: Always Steps to Reproduce: 1./etc/init.d/xdm start 2. 3. Actual Results: Xorg loads with dri disabled Expected Results: dri should be enabled From Xorg.0.log (==) RADEON(0): Write-combining range (0xf0000000,0x4000000) (II) RADEON(0): BIOS HotKeys Disabled
