@atk Good point's! I'll merge the first one, however problem with your second suggestion is, that oldIE doesn't accept the third parameter in set-timeout/interval :( The regex part looks good though!

Update

The readyState could be 'loading', 'interactive', 'complete' (http://www.whatwg.org/specs/web-apps/current-work/multipage/dom.html#documentreadystate), so we should test for 'm' or 'p' instead ;)

"interactive" seems to be the phase when the DOM is already completely parsed and only sub-resources (images, async scripts) are loaded. Seems good enough for me for DOMready.
