Thanks, I've queued this. Unfortunately it's somewhat based on luck if the automatic loading works correctly. We can't add more displays after omapfb has been probed, so all the panel and encoder drivers have to be loaded before omapfb. We have two workarounds there, which help the situation a bit. First is that if omapfb finds no displays, it returns EPROBE_DEFER. The second is that if there are displays, but no main display (display0), then omapfb returns EPROBE_DEFER. So even with these workarounds it is possible that drivers for secondary displays are loaded after omapfb, causing them to be ignored. Tomi
