These is an easy solution: doing as
`Documentation/kbuild/kconfig-language.txt' say it should be done:

config MODULES
        bool "modules ?"
        default y

config AUTO
        bool "AUTO"

config IVTV
        tristate "IVTV"
        select WM42 if AUTO

menu "TV"
        depends on !AUTO

config WM42_USER
        tristate "WM42"
        select WM42

endmenu

config WM42
        tristate
        default n
