All the boards i have either have an Ethernet Switch connected to the
MAC, or a Micrel PHY. None are setup for WoL, since it is not used in
the use case of these boards.

I think you need to scatter some printk() in various places to confirm
what is going on. Where is the WoL implemented: MAC or PHY, what is
suspended or not, etc.
