Further information. I installed XFree 4.3 packages backported to woody and then did a dist-upgrade again. This time it seems if more packages were installed as a result of dist-upgrade and after a few apt-get -f install's and a final dist-upgrade, the X11 is working again.
So what probably happened is that this morning dist-upgrade did not complete properly and you can probably close the bug. I must have tried again before submitting the bug.

He is not here; for he is risen, as he said...Therefore be ye also ready; for in such an hour as ye think not the Son of man cometh." Matthew 28:5,6; 24:44
