You can turn autocomplete off or have it only complete history/bookmarks (I just upgraded and checked.) This turns all completion off though, even URL prefix matching (as opposed to the awesomebar 'anywhere in the URL/page title matching'), which I'm guessing you don't want. There are some entries in about:config (browser.urlbar.match*) that might make it do what you want. Safari 4 does some subset of the super-matching thing too now; I find it kind of a mixed bag (I end up autocompleting to HN/twitter way too often) but am slightly on the side of it being helpful, although more intentional history search would probably work just as well.
