The OLPC utilizes a 88w8388 baseband processor along with a 88w8015 rf transceiver connected via an internal USB interface.

The XBox 360 wireless module is also based on the 88w8388 and possibly can be used with the olpc firmware: http://www.free60.org/oldwiki/Wifi_Adapter

It has now been confirmed that this is still not possible. The firmware loader on the Xbox WLAN module is not the same.--March, 2007

There is a project to take the driver developed for the OLPC and utilized it for all of the libertas family including 88w8385 cf cards: http://projects.linuxtogo.org/projects/marvell8385/

Currently there are still some issues regarding the openness of the firmware: http://dev.laptop.org/ticket/46
