Display does not return from DPMS off using ATI drivers

I've got a Turks XT and the gnome power management timeout causes my screen to turn off but it often does not come back (meaning moving the mouse and/or typing on the keyboard have wake the screen but I see only black). Attempting to switch to a terminal from out of X by using ctrl-alt-fx does not seem to enable the display either but I am able to login (without seeing anything) and reboot the box. The screen is on and wakes from sleep but usually nothing is displayed. Sometimes there is a flickering line at the top of the screen.
Relevant output from lspci:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Turks XT [Radeon HD 6670/7670]
I've attached my Xorg.0.log
Not sure if any extra info would be contained other logs (and not sure where to find them) but I would be happy to follow up if needed.
Steps to reproduce:
Login to GDM
Leave and let computer idle
Return and try to wake computer
Screen is now permanently black
