Linux WiFi driver

A opensource Linux 'airo' driver is available, and included in recent 2.6 kernels.
There is a sourceforge project page for this driver, but it seems unmaintained.
One of the developers has his own project page here, but there have not been any updates since September 2004.

In addition there is a slightly dated driver available from Cisco after jumping through a bunch of hoops, such as providing Cisco with your personal information.
The current Cisco driver version is 2.1 and only supports select Linux 2.4 kernels.
