I do it this way (via jQuery) and it works okay even when faced with  
the browser's back-button:

	function returnFalse() {
	        return false;
	$(document).ready(function() {
	        // Take care of back-button issues first.
         	$('form').find(':submit').unbind('click', returnFalse);
         	// Then wire up the auto-disabling stuff.
         	$('form').submit(function() {
         	        return true;

I don't use the 'disabled' attribute as that prevents the browser (at  
least some of them) from sending the button back to the server with  
the rest of the form.
