No they are not the same. A very brief description of 802.11 family can be found here: http://80211-planet.webopedia.com/TERM/8/802_11.html
802.11b is an extension of 802.11 to get higher speed. But I would think the Wavelan card hides the difference for the driver.
There are Wavelan drivers for both Linux and *BSD as far as I now. Maybe they can give some ideas.
