X not listening on 177 after upgrade to 7.3

Please help, I'm completely out of my league.  I know this is mostly an
Xorg question, but trying to get help from that group is ... not so

I've had the gdmchooser working for several months, now.  But recently I
updated X from 7.2 to 7.3 and X is no longer even listening on port 177:

sockstat -l46 | grep 177 

shows nothing

I see Xorg listening on port 6000, but I seem to recall that  xdm was
listening on 177 before the upgrade.  Or maybe it was gdm-binary, but
certainly it was the default port 177, not port 6000.

gdm is started by /usr/local/etc/rc.d/gdm and it runs the greeter just
fine.  But it is the chooser that I need, since I periodically need to
access this machine from the local network or from remote vpn or access
remote machines from this one.

I'm running 6.2-STABLE FreeBSD, built from source in May, so the
configuration in /etc did not change.  But it appears that my 




have been overwritten with defaults and I can't find a backup version
that works.

I expect that if I could get xdm to listen then I could figure out gdm,
again.  But I've been researching and tweeking all day and can't seem to
make it work.

I thought it was as simple as commenting out the last line in the
default xdm-config:

! SECURITY: do not listen for XDMCP or Chooser requests
! Comment out this line if you want to manage X terminals with xdm
! DisplayManager.requestPort:   0

But that does not make a difference, even after reboot.

Your helpful suggestions and insight are appreciated.
