Have you tried throwing a "magic packet" at it from a
program such as 'wakeup'?  I manage a small LAN at a site
about 240 km (150 miles) away and routinely wake
workstations for routine admin tasks.  I have an (always-on)
NetBSD box on the LAN that I can ssh to from the outside
world.  That machine has 'wakeup' installed and I threw
together a shell script that I can run to wake up all of the
workstations. If I wanted to ssh into a piece of sleeping
equipment on the LAN, I would have to wake it up before
trying to connect to it with ssh.  At present none of the
machines there are PPC or have YDL installed, but I imagine
similar techniques apply.
