xdm failing to start on FBSD 10.0 r2340030 erratically

I loose hair ...
Since yesterady's "make world" (last make world: the day before
yesterday), getting FreeBSD 10.0-CURRENT/amd64 to r234000 or so, the X11
system on all of our FreeBSD 10.0-CUR/amd64 boxes start rejecting the
start of xdm display manager. xdm is started from /etc/ttys on ttyv7.
This worked before flawless.

At this very moment, I do have X11 started via xdm - but this is a
erratic and non-reproduceable process!

This morning, I update world and kernel to r234030. I recompiled many
ports via "portmaster -f xorg xdm", hoping the new kernel/world could
affect the ports, but this isn't.

Starting Xorg X11 server works fine. xdm fails. The log in
/var/log/xdm.log looks like:

When running properly, this occurs:

Content of XSetup_0 is
#!/bin/sh
#xconsole -geometry 480x130-0-0 -daemon -notify -verbose -fn fixed

xsetroot -solid black


I feel a bit helpless around here since I can not get close to what is
happening. The erratic behaviour of starting xdm is frightening.
Starting xdm via /etc/ttys doesn't work at all, but sometimes, with a
bit luck, xdm starts when started from the console.

Oliver
