While I don't have the chipset mentioned in the bug title, I couldn't find a more generic bug for this issue. I have a Sapphire X800^2 (squared). It's identified in /var/log/Xorg.0.log as:

(--) Chipset ATI Radeon X850 PRO (R480) (PCIE) found

Running with the fglrx driver, logging out of X, trying to shutdown, trying to switch to a VC, all of these actions would cause the computer to freeze, and my monitor to enter standby mode, as it does when the computer is turned off.

Disabling dri in /etc/X11/xorg.conf did not help. However, switching to the radeon driver (I left dri commented out) fixes the problem.
