HTML5 Notifications in a Chrome extension - Can the close button be disabled?

I am using the notifications described here http://code.google.com/chrome/extensions/notifications.html for a chrome extension.

Is there any way to overwrite the behaviour of the X button (close button) which is added by default? or can I disable it?

The base layout of the notification popup cannot be modified.
There's no way to prevent the notification from being closed. Though not recommended, you can bind an onclose event, which is fired when the notification is destroyed.

I've created a demo which shows a semi-persistent notification : http://jsfiddle.net/n385r/

In a Chrome extension, the "notifications" permission has to be set in the manifest file. Then, a semi-persistent notification popup can be added as follows:

(function repeat() {
    // Assume that /icon.png exists in the root of your extension
    webkitNotifications.createNotification('/icon.png', 'Title', 'Message.');
    note.onclose = function() {
        // On close, repeat:
        repeat();
    };
    note.show();
})(); // Start the notification

My interactive demo ( http://jsfiddle.net/n385r/ ) contains more details, and the notifications can be removed. The previously shown code keeps showing notifications, until the user disabled the extension, or shuts down Chrome. As you can imagine, that's not user-friendly, and you should not use a semi-persistent notification.
