I still see SEGV in the latest mmtom (on x86-64)

drivers/input/touchscreen/Kconfig has this definition.

config TOUCHSCREEN_UCB1400
        tristate "Philips UCB1400 touchscreen"
        select AC97_BUS
        depends on UCB1400_CORE
        depends on GPIOLIB

"select" should be "depends on" ,here ?
