I think I had tried that as well, but then it seems to hang

Ah, ok. Never heard of but it seems to be selected automatically:
CONFIG_CONNECTOR=y
CONFIG_DRM_DISPLAY_CONNECTOR=m
and
root@letux:~# lsmod | fgrep dss
omapdss 163840 3
omapdss_base 16384 2 omapdrm,omapdss
drm_kms_helper 143360 3 omapdss_base,omapdrm,omapdss

cec 45056 1 omapdss

Does the panel driver also need some modification? It is no longer loaded.
BR and thanks,
Nikolaus
