Description (last modified by )
We need to generate fake edid information based on the output of a special LVDS information AtomBIOS call.
The lack of this information prevents several laptop LCD displays from modesetting properly.

It should be noted that the special display port LVDS bridge in newer 6xxx hardware is working. We're actually doing pretty good as this issue the easier of the two methods to implement.
