Here is my script that takes care of this with sudo ...

## xsudo() ##########################################################
# A wrapper for sudo that passes the existing Xauthority cookie from
# a privileged location to root.
xsudo() {
        for i in /usr/X11R6/bin/xauth /usr/openwin/bin/xauth; do
                if [ -x ${i} ]; then
                        XAUTHEXEC=${i}
                        break
                fi
        done

        if [ -n ${XAUTHEXEC} ]; then
                sudo  ${XAUTHEXEC} -f /root/.Xauthority add
`${XAUTHEXEC} list ${DISPLAY}`
                XAUTHORITY=/root/.Xauthority sudo $*
                sudo ${XAUTHEXEC} -f /root/.Xauthority remove ${DISPLAY}
        else
                echo "Error: No xauth found."
        fi
}
