linux-wlan-ng-source 0.2.3-1ubuntu4 (i386 binary) in ubuntu dapper

 linux-wlan-ng is a set of drivers and utilities that is intended to
 provide the full range of IEEE 802.11 MAC management capabilities for use
 in user-mode utilities and scripts. The package currently supports the
 Intersil 802.11b Prism2, Prism2.5, and Prism3 reference designs for
 PCMCIA, PCI, and USB. Additionally, the package includes support for the
 PLX9052 based PCI to PCMCIA adapter with a few different PCMCIA cards.
 .
 This package provides the source code for the linux-wlan-ng kernel
 modules. After installing this you must use module-assistant to compile
 and install the modules.
 .
 Please note that you probably do not need this package on Ubuntu: the default
 kernel already ships all necessary drivers.
