Hola

Creo que esto te servirá:
Código PHP:
<html>
<head>
<script type="text/javascript">
function validar(frm) {
for (i=0; ele = frm.getElementsByTagName('select')[i]; i++)
if (ele.selectedIndex != 0) return;
return false;
}
</script>
</head>
<body>
<form action="tupagina.php" onsubmit="return validar(this)">
<select>
<option>----</option>
<option>opción 1</option>
</select>
<select>
<option>----</option>
<option>opción 1</option>
</select>
<input type="submit" />
</form>
</body>
</html>
Saludos,
