This is somewhat of a coincidence. I only found this out last night
after updating /etc with the latest rc.conf commits (which work fine,
btw, apart from a missing keybell= definition).

xdm startup just needs to be delayed until /etc/rc completes. My
gut feeling is that there's definitely a race condition here that
should be solved "correctly", and that as machines/disks become
faster we're more likely to see this in the future, especially if
xdm is started before other things from /etc/rc.local or from
/usr/X11R6/etc/rc.d.

The workaround I ended up using is:

if [ X"$1" = X"start" ]; then
	echo -n ' xdm'
	(sleep 15; exec limits -C xuser /usr/X11R6/bin/xdm) &
fi

(remove "limits -C xuser" if you're not using -current.
