X server log with -logverbose 7

I know that R600/700 support is still experimental, but mode setting should
work OK already, right?

I have a new AMD 780G motherboard connected via HDMI to a Samsung DLP TV. The
TV supports the modes 1920x1080, 1280x720 and 640x480 which are correctly
recognized by the driver. The TV also shows that the mode has been correctly
negotiated. But only the middle part of the screen is actually visible, e.g.
roughly 1800x1000 when using the 1920x1080 mode. Additionally in the 1920x1080
mode the X11 background is displayed with a moire pattern.

I tried with the latest git master (38aa450fc) and X Server 1.5.0 on Fedora 9.
