WOL works fine if the system is powered down. it does not work with echo mem/disk > /sys/power/state. for disk, it does not matter whether /sys/power/disk is platform or shutdown. # lspci -vv 00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 03) Subsystem: ASUSTeK Computer Inc.

Closing as obsolete, if this is still seen with modern kernels please re-open and update
