[jQuery] Conflict with Yahoo UI

[jQuery] Conflict with Yahoo UI

I was building a sortable list in activeCollab but the <ul> wouldn't work correctly and $.Sortserialize doesn't seem to exist.  The minute I remove  yui/yahoo/yahoo-min.js or yui/dom/dom-min.js  the jQuery Sortable works great.
Here is my ul.Sortable
--------------------------------
$('ul').Sortable(
    {
        accept :         'sortableitem',
        activeclass :     'sortableactive',
        hoverclass :     'sortablehover',
        helperclass :     'sorthelper',
        onchange: function(s) {
            serial = $.Sortserialize('sort1');
            $.post("index.php?c=dashboard&a=sort_priority",{params:serial.hash
});
            //alert(serial.hash);
        },
        opacity:         0.5,
        fx:                200,
        revert:            true
    }
)
I get errors that say $.Sortserialize is not a function and $("ul") has no properties when the Yahoo UI libraries are loaded.  I tried putting the jQuery includes befre and after the YUI include.  No luck.  Any idea how to work around this without eliminating the YUI libraries?
I want to use jQuery but I might be stuck using YUI if this problem persists.<br clear="all">
