	For what it's worth, I have a Tyan S2469GN with dual
Athlon MP's in it in a 3U rack mounted case.  The power button
acts as any other ATX "soft" power button I've ever seen, which
is to say, it does nothing unless I hold it down for four
seconds, at which point, all power is cut to the machine and it
is officially off at this point.  This is regardless of the state
of the OS.

acpi0: power button is handled as a fixed feature programming model.

and sysctl:

hw.acpi.power_button_state: S5
hw.acpi.disable_on_poweroff: 1

	I'm running 5-CURRENT from a few days ago...
