Sorry I pasted in the wrong version, from an older machine.  Here's
what I have on my own Fedora 12 box after the lines creating the
directory in /tmp and setting XAUTHORITY:

if [ "$DISPLAY" = "" ]; then exit 0 ; fi
if read proto cookie && [ -n "$DISPLAY" ]; then
	if [ `echo $DISPLAY | cut -c1-10` = 'localhost:' ]; then
		# X11UseLocalhost=yes
		echo add unix:`echo $DISPLAY | cut -c11-` $proto $cookie
	else
		# X11UseLocalhost=no
		echo add $DISPLAY $proto $cookie
	fi | xauth -q -
fi
