Can I wrap a javascript event in a jQuery event?

I have this code:

<html>
<head>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
    <script type="text/javascript">
        $(function(){
            $('a.one').click(function(event){
                event.preventDefault();
            });
        });
        function test(event){
            event.preventDefault();
        }
    </script>
    <style type="text/css">
        a.test { font-weight: bold; }
        body { font-family:sans-serif; background-color:#AAAAAA;}
    </style>
</head>
<body>
    <a class="one" href="http://jquery.com/">jQuery</a>
    <br/>
    <a class="two" href="http://stackoverflow.com/" onclick='test(event)'>stack overflow</a>
</body>
</html>

The test-function does not work as it stands now, since a regular javascript event doesn't support the jQuery event preventDefault-function. Is there some way to wrap a regular javascript event in a jQuery event so that I can use e.g. preventDefault?
