I can't really answer your question, but there's an alternate
solution. You can use a device which delays the booting of some
nodes. For example, the APC MasterSwitch has the ability to let you
power cycle nodes by attaching to a web browser, but another feature
is that it can power up the nodes with a delay after a power failure.
It's a bit expensive for this purpose ($354 for 8 plugs @ 120V, 12A
total), but maybe you can find something cheaper, such as an X10 based
controller.
