Sigh. A debugging message left at DRM_ERROR.

This is just an info message as a few kernel releases ago we started
honouring LVDS sync from the EDID and so we wanted to make sure that no
regressions correlated with actually doing as we were told.

This is one the true error in the midst of this spew.

Aside from the one modesetting error, these messages are all secondary
to the crash (and are really just debugging spew whilst switching
modes from X to console, console to X). Can you please attach the
Xorg.log containing the crash? Or maybe gdm.log etc? Also what happens
regularly every 30minutes; a particular screensaver or dpms?
