You need a real Cisco card to do LEAP (using a PCMCIA/CF adapter). on homepage.mac.com/tz1 I have leapauth with source(?) as leapz.tgz I also have some xsupplicant stuff there.
I think the other parts needs hostap or prism2 drivers, but they also compile for the Zaurus. I don\'t have a EAP access point so I don\'t know.
