The OLPC panel seems to be connected to DVP1 and LVDS2 for some reasons and if not both are handled correct the display does not work correct or not at all. This patch prevents regressions on the OLPC where it worked by accident but would break in future as the driver did not know the correct devices connected. This might also fix hardware scaling. Hopefully the OLPC is the only device with such a requirement but it will be certainly better to actually know what devices are actually connected and to not work by accident.
