Pressing CTRL-ALT-F1 will not get you out of the loop of death but it
will avoid you frying your monitor.  Until we can assume than X will
work out of the box (not in a long time) putting people in XDM without
having given the user the opportunity to verify than it works is not
the way to go.  I really don't see what is wrong in having the user
start X manually once in his life.

Windows detects problems when the user does a CTRL-ALT-DEL just after
boot, in that case it enters failsafe mode.

Unless than you can provide an analogous mechanism (difficult because
X grabs keyboard) stiop dreaming about an all XDM distribution.  For
now X has no mechanism to know if the monitor is displaying correctly.

Also try to think what happens if user changes video card and you drop
into XDM..
