[IE6] Siamo alle solite... (float, padding, margin)

Salve, per godermi le mie meritate vacanze devo finire questo sito (clicca qui ) fatto con joomla. Usando firefox funziona una meraviglia però il mio cliente ha IE6 e giustamente rompe perchè si vede male... ho provato di tutto... ora mi appello a voi.
Su IE6 il footer è l'unico che si trova nella posizione giusta mentre gli altri no...

ora vi posto un pezzo di index.php e un pezzo del css...

<div id="wrapper">
	<div class="inside">
    	<div id="header">
        	<div class="headermenu">
        	<jdoc:include type="modules" name="top" />
