It is possible for `css3ie-loaded`.  The `equalize-loaded` event was added recently by me, so it's unlikely that anyone has hooked into it.

Initially I had the code like so for the pull so that both events would continue to fire:

```javascript
if (pe.ie > 0) {
	pe.wb_load({'plugins': {'equalize': pe.main}}, 'equalize-loaded');
	if (pe.ie < 9) {
		pe.wb_load({'plugins': {'css3ie': pe.main}}, 'css3ie-loaded');
	}	
}
```
But the above was giving a script error in IE8 from [$.globalEval](http://api.jquery.com/jQuery.globalEval/) (the extremely helpful "Could not complete the operation due to error 80020101").
