Linux Wi-Fi driver
A free Linux 'airo' driver is available, and included in recent 2.6 kernels.
There is a sourceforge project page for this driver, but it seems to have been abandoned.
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 'mpi350' 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. The Cisco driver does not support Linux commands such as iwconfig. However, one can use the Cisco ACU GUI with the Linux 'airo' driver for read-only status information.
OS/2 and eCS driver
This card should be supported by GenMAC 2.20 and above.
The older airo or mpi350 drivers might not work with certain (more recent) Cisco firmware. Evidently there is a Windows tool allowing you to modify the firmware, but if you already nuked your win32 partition, you'll be in a pickle. For Linux 2.4, you would want an older firmware version 5b00.08 or 5.00.03, which is packaged with version 3.4.9 of the Cisco Windows drivers.
The above described problem does not apply to 2.6 kernels. Cisco updated its mpi350 driver and the fixes have been reverse-engineered and incorporated in the open-source airo driver for Linux 2.6. I.e. Cisco firmware version 5.60.17 and 5.20.17 work with Linux 2.6.11 and airo driver 0.6. The firmware is upgraded under WinXP automatically with Cisco driver updates. Older firmware also works with the Linux 2.6 driver
