Something to mention about WOL, is that it is effectively a hardware thing. When a network chip sees some special network packet, it will generate a PME signal that _should_ cause the hardware to power up and do what it should on that power state transition.
Where software is involved, is in the configuration and enablement of the feature. IOW, if the software turns off the network hardware, it won't be possible to see the network event that will cause the PME generation. In current Solaris, a shutdown will take all the devices offline, and prevent wakers that are not directly wired to the machine (such as the soft-power button, or some internal alarm device) from actually waking the machine. In the near future, this will not be the case, and legitimate S3/S4 waking devices will be allowed to generate a PME if either the driver allows it or the BIOS allows it (BIOS enabled wakers _will_ wake the machine if not disabled by the driver in some way).
