dmesg output

- starting or running an X session
- using DirectFB to e.g. play movies in vlc or mplayer from a console login
circular locking dependency warnings appear in dmesg.

Afterwards, X can hang or crash outright but at other times does not appear
affected.  Video output in framebuffer is always highly corrupted (not sure if
this is a separate bug).
