It depends on the hardware and the driver. Is this a specialized sort of USB WLAN device with features specific to the XO? How is the sideband wakeup signal implemented? Does the driver know that it is running on an XO? Does the driver know that this sideband signal exists? The easiest answer is for the driver to call directly into the platform code.
