As far as I know you a malicious site can't fake a referer header* (unless maybe if you allow cross-site XMLHTTP - but all modern browsers prohibit that - right?)

Never trust the browser

Yes, but I was talking about malicious sites faking referers without the user's explicit permission. If a user wants to forge a referer header there's no way to stop it. Note that we're trying to protect the user, not the web app per se.
