[beagleboard] No /dev/input/event*

HI,

I hope someone can point me in the right direction.

I've configured my kernel for:

CONFIG_INPUT_EVDEV=y
CONFIG_INPUT_KEYBOARD=y
CONFIG_KEYBOARD_GPIO=y

Yet when I look in /dev/input there are no files (devices).

I would like to be able to use the USR button on my C4 beagleboard to
kick off a whole lot of things in my test app under my control. I
don't haev any other external keyboards or anything connected or
configured yet. All I need is a simple push button interface for now.

Thanks,

Richard.
