If you fire up DisplayConfigX, and click on the install tab, it tells you where the overrides file is stored for the selected monitor.
It is the part after the "rm " in the removal instructions.
It should take the form of something like this:
/System/Library/Displays/Overrides/DisplayVendorID-xxx/DisplayProductID-yyyy
Where xxx and yyyy depend on the monitor. (Make sure you have the correct monitor selected at the top of the DisplayConfigX window so it shows you the matching filename.)
You should be able to copy that file from your backup... make sure to match the privs once the copy is done.
