Code:

root@pi ~ # find /lib -name led*
/lib/modules/3.15.8+/kernel/drivers/leds
/lib/modules/3.15.8+/kernel/drivers/leds/trigger/ledtrig-camera.ko
/lib/modules/3.15.8+/kernel/drivers/leds/trigger/ledtrig-transient.ko
/lib/modules/3.15.8+/kernel/drivers/leds/led-class.ko
/lib/modules/3.15.8+/kernel/drivers/leds/leds-gpio.ko

Code:

root@pi ~ # modprobe leds-gpio

And tadaa:

Code:

root@pi ~ # ls /sys/class/leds/led0/
brightness  device  max_brightness  subsystem  trigger  uevent

Thanks, you learn something new every day! One comment, to anybody else doing this: I had to run modprobe from /sbin
