Its becoming a pretty common practice to charge extra for IE6 support. If you hate IE that much its always an option to charge for the full gamut, but don't act surprised when the phone stops ringing as much ;)

On a serious note, IE has always been a challenge for front end dev, but its at least up front about its lack of support. Chrome, FF and Safari will sometimes have a minor margin bug that will drive me more insane then the expected behavior of IE.
