Here's what I do.  The hook to use is xrdb, which is (currently) called
from xdm with two arguments, -d and -l.  You may find better directories to
put things in.

In my xdm startup line, I point to an xdm config file.

In the config file, I have this:

  DisplayManager*xrdb:		/etc/xdm-xrdb

Here's /etc/xdm-xrdb:

  #!/bin/sh
  rfile=
  while [ $# -gt 0 ]
  do
   case $1 in
   -d*) DISPLAY=$2; export DISPLAY; shift;;
   -l*) rfile=$2; shift;;
   esac
   shift
  done
  # Set a shaded background (DECstation has 864 pixels vertical)
  /usr/bin/X11/bggen -b 7 -s 864 45 90 180 20 30 80 |
    /usr/bin/X11/xsetbg stdin >/dev/null 2>&1
  # Really run xrdb
  /usr/bin/X11/xrdb $rfile
  exit
