I think you can do this with OpenAP if the original AP and the repeater are 
running OpenAP code. Since OpenAP is a Linux distribution designed for 
certain (AP) hardware, it would also be possible to port to a standard 
computer. (There have been a few people asking if ports are available but I 
don't think I've seen any positive replies).

If you can use two cards rather than just one, you could run one card (any 
type) as a client to the original AP, and a second either in ad-hoc mode 
(to other ad-hoc clients) or if the second card is a prism2, you could use 
Host-AP mode.

If you don't already have hardware to run it on, the Soekris net4521 and 
Musenki m-3 will (when available) support a couple of wireless cards and 
allow you to run an open OS which would be quite suitable. (from 
soekris.com - net4521: waiting on cases, should be available soon. from the 
Wiki at musenki.com: "Production shipments are scheduled for the June/July 
timeframe").

Some ready-made APs may be suitable but usually need similar kit at each AP 
site. It looks like the Buffalo 22mb APs might be able to repeat a wireless 
connection when associated with another Buffalo 22mb AP. There should be 
more options as you go further up the price range (probably Cisco and 
possibly Orinoco). Using the ap-client mode in atmel-based APs (WAP11, some 
SMC, Netgear) you can do

AP --(wireless)--> AP-client --(x-over ethernet)--> AP --> client

May not work depending on the particular combinations of kit though.
