Linux WiFi driver
The most recent revision of the Intel Centrino platform does utilize a new generation of wireless networking device, connected to the system via PCI-E, and not PCI (like the ipw2200-line used to do). Therefore, a new driver is to be used. A sourceforge-project aimed to support the new cards is available on http://ipw3945.sourceforge.net/. However, as of today, the project's code (which is not in production stable condition) depends on a binary-only, proprietary user-space-daemon communicating to the driver via sysfs. It is not possible to operate this device with Free Software exclusively at the moment. The license-terms the daemon is released under prohibit reverse-engineering of the communication-protocol, this will hopefully not hold developers from countries other than the US, where clauses like this one are not enforceable, from re-implementing a free variant of some sort.
External Discussion
This issue already sparked discussions on the LKML, accessible via http://lkml.org/lkml/2006/2/24/266.
Current State
The ipw2200-drivers in kernel 2.6.15 (and possibly later) do not work with this adapter. There is no mainline-kernel support at the moment, and without a change in the license of the required user-space-daemon, or mechanics of the code itself, probably will never be any.
