Have a look at http://hostap.epitest.fi/hostapd/ for more information. You'll definately find Prism 2/2.5/3 and possibly Prism 54 Compact Flash cards, although you may find ebay is the only place to buy them these days. For the atheros one's I think the only option might be USB. > 3.

A Linksys WRT54GL would work fine for this but its a quite large and (compared to a gumstix) power hungry.
