This sounds a lot like this commit from upstream drm:

drm/i915/lvds: Always restore panel-fitter when enabling the LVDS
Linus Torvalds pointed out that our code was unbalanced when powering on
the panel with respect to the power off sequence in that we were failing
to restore the panel-fitter. The consequence of this would be that
across a simple DPMS off/on for a non-native mode, without an intervening
modeset, the panel fitter would remain disabled and the output would shift
on the panel.
Do you see this issue with an upstream 3.6 kernel? 6.4's DRM will be rebasing to 3.6 + fixes.
DRM rebase has been merged containing the above fix, and will be included in RHEL 6.4 If you can still reproduce this issue on an upstream 3.6 kernel (Fedora 18, for example), please reopen this issue.
