Well that doesn't tell us anything we didn't know already, does it
There seem to be a lot of problems with that chipset on linux, i found two other threads on your card, one of them here in linux questions
If my interpretation is correct, you're going to need to use your windows drivers, so have those handy. You'll also need to install something called ndiswrapper, that makes some windows drivers work on linux. You can find a guide for this here:
The guide only mentions support until 9.10, but it'll probably work on 10.04. The guide may look big and intimidating, but the ubuntu community is usually very newcomer-friendly so I think you'll manage
Also, it only mentions usb and pci cards, not pcmcia, but try it nevertheless.
I don't know if I can be of much help from here on, if that procedure doesn't work you're kind of stuck... But feel free to ask if you have any questions
