Xorg.0.log with repeated switches to 800x600 and back to 1280x1024.
When I switch to a resolution below 1024x768, the screen gets blanked and my
lcd reports that the incoming signal is out of range. This happens with all
radeon and radeonhd drivers which support my Radeon 4670 RV730XT, but only with
DVI output, VGA seems ok. It looks like the drivers calculate wrong modes but
strangely only at low resolutions. The Option "DefaultTMDSPLL" doesn't help,
neither enabled nor disabled.
