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.

OK, 1/2 is already in and I applied 2/2 manually. Still no picture on screen :(

Then I used this uSD card in a different board and I get the orange u-boot screen and later a GNOME desktop. So it seems I tested it with a broken board :/
Nevertheless, everything as builtin is still broken, but with modules it seems to work.
