Comment 36 for bug 712075

@Ernst: You're saying that you saw the behavior regress in maverick when you did updates, correct? You don't happen to know the kernel versions before and after the update, do you?

Suspiciously, there's a patch dealing specifically with EDID handling on Intel graphics that would have first gone out in maverick in that general time frame. It's was first released upstream in 2.6.37-rc8.
