The TS-7xxx boards don't have power supply control on them like a ATX PC
would. The reason the OS on a ATX PC can shut itself down is because
there is a small power management circuit that's always powered by the
power supply, this circuit when you press the power button grounds one
pin on the PS connector causing the PS to turn on (you can do it
yourself by shorting the green wire to ground on a standard ATX power
supply.)
The TS-7xxx doesn't have this, power goes in, goes through regulators,
and powers the components. You could easily modify init or your
shutdown scripts to bring GPIO high that's connected to the release on a
latching relay (with some glue circuitry since I don't know of any
latching relays that run on 3.3v), or build a latchign circuit with two
relays.
