A firmware update package for the wireless function of this adapter is available from IBM.
The available firmware version is and is available here

The firmware update can only be run from Windows

Linux WiFi driver

This adapter works with the 'orinoco_pci' driver as part of any recent 2.4 or 2.6 kernel.
In addition the 'hostap' driver can also be used.

Linux Modem driver

The Linux driver from SmartLink supports this device.
Latest version of this driver is 2.9.10 and supports both the 2.4 and 2.6 kernels. The modem works with the "ALSA method" which is detailed in the README that accompanies the SmartLink driver.

Note! Since kernel 2.6.12, there is new ALSA mixer control "off-hook" which has to be unmuted before the modem can be used, e.g. by running "alsamixer -D hw:1".
