You don't need a patch! It's already there, even if it's kind of a _hack_:
If used the following to display xmas-bitmaps: (of course you have to be
root/have write acces to the files/directories)

in /usr/lib/X11/xdm (default directory for xdm configs)

change/add the line in xdm-config:

DisplayManager*xrdb:           /usr/lib/X11/xdm/xrdb+xsetroot


make the file /usr/lib/X11/xdm/xrdb+xsetroot to look like e.g.:

#!/bin/sh
#
# load the resources and change the root-window background pixmap
#

/usr/bin/X11/xrdb "$@"

echo "setting root background" >> /usr/lib/X11/xdm-errors
/usr/bin/X11/xsetroot -display $2 -bitmap /usr/wiss/stumpf/bitmaps/xmastree.xbm
exit 0


To really get it to work, you have to kill all xdms and restart xdm!
