It's possible that the Intel driver could use the same trick the Nouveau module does. Nouveau also had lid-detect quirks, which they removed, and now the driver reports LVDS as “unknown” if the lid is detected as down. If there are no other outputs detected, the “unknown” status causes nouveau to try to bring up the LVDS anyway, and if there are other outputs connected the LVDS remains unactivated.

This seems like a better behaviour to me.

That still leaves the DVI powering off problem, though.
