INF driver file? What kind of Linux distribution are you talking about? I guess you mean using ndiswrapper? But what kind of linux user would say "use the INF file" instead of "use ndiswrapper?"
Seriously, though, it looks like ndiswrapper (it's a tool that lets you use Windows drivers in Linux; it's primarily used when Linux native drivers are not available) is the best option right now (it's not ideal, but it works). It'll work, as above, on almost any Linux variant. There's a walkthrough for Ubuntu 8.04 here:
This is the part where you're likely to annoy people because you're not even making a token attempt to pay attention to the answers you're receiving.
1) No, 7.10 is not the most recent version of Ubuntu. 8.04 is; it was released in April. Just going to the Ubuntu website would have answered this question.
2) I just posted a link that describes in detail what does and doesn't work in Ubuntu 8.04, including the Wireless (which does work, using ndiswrapper).
