I wouldn't have thought reacting to a WOL wakeup would need to be any different from the normal power-button wakeup. The problem at the moment is that it doesn't seem possble to suspend the machine in such a way that it will wakeup at all in response to network activity - either magic packets or other. Is this what the 2.6.32 work is intended to solve?
