I've also wondered if an old PCI modem card might be used in various 
ways.  Mimicking a "ring in" in many cases can be configured to wake a 
system and is probably very widely supported from what I've seen of 
motherboard BIOS.

Many of the modem cards have a relay that might also be switched by 
sending modem commands.  The relay outputs can be commandeered to some 
useful purposes, e.g. being the initiating switch to powering all other 
devices.

The cost of these unwanted cards is also negligible these days.
