No, Virtualization software can't take control of pci devices.
No, there's no fix for this besides buying a new one (USB).
No, you haven't searched before posting.
EDIT: As you posted another thread on the same issue, maybe I wasn't clear enough. When I said "No, Virtualization software can't take control of pci devices.", this means that vmware won't be able to use your internal card as a wireless card.
As for your "if i need just tell me the list of wifi cards that i need to buy in my vista laptop???" question you posted on the other thread, there are more than enough posts about wireless adapters on the forums (check the HCL forum). Again, a quick !SEARCH! would have avoided this question.
