That sounds quite odd.. Did I understand it correctly: with AP running hostap 2002-04-21, station using Orinoco card (wvlan_cs/orinoco_cs driver) works fine, but 2002-04-24 or anything newer on the AP causes the station to panic? Can you repeat this?

Indeed it sounds strange. I have had no problems with using orinoco_cs as the client with hostap driver being the AP, but I would have to admit that I'm still using an ancient version of orinoco_cs (0.08a from Oct 2001). Which version of the orinoco_cs are you using? wvlan_cs/orinoco_cs do not handle management frames on the host driver, so this would need to be something else. I would also be suprised if encapsulation/decapsulation of data frames had such a bug.
