The xdmsc init script that ships with SUSE 10 (boxed copy at least), is completely unprepared for xorg instead of xfree. Specifically, the get_version() function looks for:

        case "$l" in
            XFree86\ Version*) break ;;
        esac 

instead of:

        case "$l" in
            X\ Window\ System\ Version*) break ;;
        esac 

and:

    case ${3%%.*} in
        [0-9]) echo ${3%%.*} ;;
        *)     echo 0        ;;
    esac

needs to use:

    case ${5%%.*} in
        [0-9]) echo ${5%%.*} ;;
        *)     echo 0        ;;
    esac


Thanks!
