The old one is, the newer one is ADMtek and its hard to find the old one nowadays, the Netgear PCI card is about the only one that is still prism2, make certain to check the linux-wlan list:
http://www.linux-wlan.org/docs/wlan_adapters.html
Anything there prism2/2.5/3 will work with the the orinoco_cs module, its onboard, most of the GUI network configurators will set it properly.
