That would be fantastic.

Green status: 62, green, active low
Red status: 63, red, active low
HDD racks: 70 to 75, red, active low
USB: 17, blue, active low

I tested all via sysfs with gpio-f7188x driver loaded (numbers above
are the values I wrote to /sys/class/gpio/register).

"green status" led works minimally out of the box: static-on when the
box is on, off otherwise (I would make it blink on S3, for example).
