We have two sources of information about panel capabilities on mobile radeon - the BIOS, which gives us a native mode, and the panel's preferred mode. In theory these two will always match, but there's some corner cases where the BIOS hasn't been fully initialised and so the native mode in it ends up with default values. However, if we get a panel with reasonable EDID, it's probably the case that the panel's preferred mode does actually represent the panel capabilities. This patch handles that case by replacing the native mode with the panel's preferred mode if the resolutions don't match. Systems without a valid internal panel EDID will still use the BIOS native mode.
