The Marvell wireless chip we're using this generation in the OLPC machine is interfaced via USB. Not ideal, but there's no other game in town to let us keep the mesh network up while the main machine is STR. We intend to leave the Marvell chip on (it can forward packets in the mesh network, and/or wake up the CPU if there are inbound packets for the machine that matter), and turn off the USB interface it is attached to.
