In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Shared driver code for IEEE 802.11b wireless cards based on
Intersil Prism2/2.5/3 chipset. This driver supports so called
Host AP mode that allows the card to act as an IEEE 802.11
access point.

See <http://hostap.epitest.fi/> for more information about the
Host AP driver configuration and tools. This site includes
information and tools (hostapd and wpa_supplicant) for WPA/WPA2
support.

This option includes the base Host AP driver code that is shared by
different hardware models. You will also need to enable support for
PLX/PCI/CS version of the driver to actually use the driver.

The driver can be compiled as a module and it will be called
"hostap.ko".
