[jQuery] Extend/Override jQuery Functions for IE6

[jQuery] Extend/Override jQuery Functions for IE6


After days of searching and experimenting with solutions for IE6
issues (peekaboo, etc.) I am having with my css implementation and
jQuery, I believe a temporary work around is to extend/override (not
sure what the exact term is) some jQuery functions when used in IE6. I
am sure there is an actual solution that would involve fixing my css
and/or js code, but given my project's current time constraints, this
will suffice.
HTML head:
<script src="_assets/js/lib/jquery.js" type="text/javascript"></
script>
<!--[if lte IE 6]>
<script src="_assets/js/lib/ie6.js" type="text/javascript"></script>
<![endif]-->
And code like the below within the ie6.js file (i'm running into
issues with slideDown, slideUp outside of quirksmode):
jQuery.fn.extend({
        slideDown: function(){ $(this).show(); },
        slideUp: function(){ $(this).show();}
});
I would greatly appreciate feedback, suggestions, corrections and help
concerning any issues that may arise with this approach:
