On my box poweroff does just that as far as I can see.

I'm running a 2.4.25 kernel and did try the kernel acpi support but I 
couldn't use a clean shutdown and get the box to power on. Only if I did 
an unclean power off that just kills the machine in an instant with
# echo 1 > /proc/acpi/sleep

But nvram-wakeup really works great on my box.
