This is so that people don't cause their suspended laptops to wake up by unplugging a USB mouse, for example. If you want to enable wakeup, you have to do it manually or from a boot-time script like /etc/rc.d/rc.local. For example, you might need to do: echo enabled >/sys/bus/pci/devices/0000:00:04.0/power/wakeup The system has been this way a long time, but up until just now it didn't work correctly.
