I have run into this problem too. I have been using the max-width css tag on the main parts of the page to limit the width. Now I know that IE doesn't support this, but I have run across a few tricks to get it to work until they do support it. This can allow some fluid design for most resolutions up to a specific width (I usually us max-width of 1024px). This covers the majority of screen resolutions from the visitors to the sites I work on.
