I was wrong about this. With this change xdm started fine from the command line 
and took perhaps even longer when started from /etc/ttys. This describes 7.4_1 
behavior.

All these issues are with xorg 7.4_1. I have installed xorg-7.4_2 via pkg_add on 
a clean system and xdm-1.1.8_2. Nothing else is installed.

Starting xdm gives the following in /var/log/xdm-log:

      :
   finished PLL1
   set RMX
   set LVDS
   enable LVDS
   disable primary dac
   disable FP1
   disable TV
   /libexec/ld-elf.so.1: /usr/local/bin/X: Undefined symbol "shmctl"
   xdm error (pid 1416): server unexpectedly died
   xdm error (pid 1416): Server for display :0 can't be started, session
   disabled

I added one line to the xorg.conf file generated by Xorg -configure:

   Option      "AutoAddDevices" "false"

A diff shows this file to be exactly what I was using with xorg-7.4_1 (which 
works albeit with a very slow startup). I have excerpted various 
[relevant] outputs to show my hardware. I needed I can either attach or 
include the entire files.

startx works but locks the keyboard. After running fsck scores of times, it 
finally occurred to me to ssh into the system so I can force a shutdown. With 
both startx (which appears to work) and xdm a reboot is required to recover 
the system. Starting xdm get an error logged to STDERR that an IPV6 LISTEN can 
not be done.

My laptop is built without IPV6. hal and dbus are not started.

Thanks for any help. This appears to be either an error in the way the package 
was build or something I can [hopefully] configure around.
