x86: Xorg Does Not Use the RadeonHD Driver Without the xorg.conf File (6642276)

The Developer 1/08 release includes a video driver for ATI Radeon X1000 and ATI Radeon HD2000 series graphics cards and chipsets. Xorg will not detect and use the new driver unless it is specified in the xorg.conf configuration file. Xorg attempts to use the VESA driver instead, which might not work on all Radeon graphics devices. No error message is displayed.

Workaround: Type the /usr/X11/bin/Xorg -configure command to generate a /etc/X11/xorg.conf file after installation. Verify that the xorg.conf configuration file specifies the RadeonHD driver.
