Comment 19 for bug 66696

OK, the orinoco dkms package in my PPA does compile all right, and gets loaded after reboot. It also loads a firmware file if I copy it to /lib/firmware/agere_sta_fw.bin. So far the package does not include such a firmware file, in order to avoid possible collisions with future Ubuntu packages. You have to copy the firmware yourself for now.

So much for the good news. The bad news is that with the agere firmware I pointed out above my card still fails to establish WPA connections. Lots of messages in dmesg, most about dropped info frames or some such, which I take as an indication that this firmware is not for the hardware I have, some old Toshiba Mini-PCI card. I also couldn't find a Windows driver capable of WPA for this card, so using the agere_fw_utils to extract the firmware from windows drivers isn't an option either, and it might be the hardware can't support WPA with any firmware.

So I can't give you an answer as to if this driver would enable WPA on orinoco_cs cards, given the correct firmware. Please try this yourself, see if it works for you or not, especially if you have WPA working on Windows.
