JFTR, the branch mru/x_rewrite contains a new grml-x which does not generate a xorg.conf at 
all. Ch suggested (I'll second that) that we rename the original script to grml-x-legacy. 

I send a patch removing the startx/xinit functions to the grml-etc-core mailinglist as there 
is no longer a need to run grml-x. 

I also suggest that we change x-window-manager to wm-ng, as the new grml-x does not need an 
specific window manager but should start with sane defaults (issue925)
