You could use a cf-stix on a connex. I use this configuration with a
selection of Dlink, Pretec and Linksys CF wireless cards to turn a
gumstix into an access point.

Cards using the Prism 2/2.5/3, Prism 54 and Atheros ar521x chipsets

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

You could plug the gumstix into an access point over ethernet and bridge
it. A Linksys WRT54GL would work fine for this but its a quite large and
(compared to a gumstix) power hungry.
