 +Code has been commited in linux-2.6 main git tree as seen here http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=a88656553d18c324554855fccc730c9644048111.
 +So LED will soon be controllable from userland. **Expected in 2.6.31**
 +discussion with Erik Benada explaining that :
 +with conversion of Orion architecture to gpiolib it is now possible to
 +turn off power LED blinking from userspace - eg. after booting is
 +finished. You can also turn on power LED blinking before you shut down the system to let user know system is going down.
 +To turn off power LED blinking after booting is finished:
 +          echo 1 > /sys/class/gpio/gpio3/value
 +To turn on power LED blinking before shutdown/reboot:
 +        echo 1 > /sys/class/gpio/gpio4/value
 +Disk access leds still don't work properly in 2.6.32...
 +Following code configures SATA gpio, not ARM gpio
 + writel(0x00000050, mmio + MV_GPIO_PORT_CTL_OFS);
