If I statically build in everything the drm encoders and connectors all go into deferred probe mode and fail, falling back to 1024x768. I with omapdrm and encoders/outputs/etc as modules deferred probe is avoided, far fewer error messages and a 1280x1024 resolution is being used. But still the monitor still says 'no signal' detected.
