Well with FC2 the box would powerdown and trivial power
would be available to the network card and with a correctly
formed packet the card would wakeup the box (equivalent
to pushing a front panel button).

I guess it partly depends on the state that the system leaves the network chips 
and PS when the box is shut down.  In this case:

 eth0 = Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 74)

I suspect some of the key difference is with acpi_power_off
While acpi is enabled for the BIOS on both the FC2 and FC3Test3 box
only FC3test3(and2) is noisy about using it on powerdown.

I think the rock I need to look under is acpi_power_off.
