Wake On LAN should actually be able to wake a system up from power off state, so it should reasonably work for suspended systems too. As a first thing, the NIC LED (or the LED on the ethernet switch) should be on; it will be on even when the system is switched off, if WOL is active. Then WOL has to be enabled. You can trust the BIOS or, better, run ethtool eth0 and you will get something like Supports Wake-on: pumbag Wake-on: g which (according to the man page) means WOL on my machine will respond only on a specific kind of packet. Last step is sending a proper WOL packet to the machine you want to wake up (use wol or wakelan). Be sure to use the correct interface on the waking machine and also try to write the MAC address with reversed bytes (that is try 11:22:33:44:55:66 and 66:55:44:33:22:11); don't ask me why, but I have two machines where only the inverted MAC works.
