IE Unlimited CSS Loader | drupal.org

This module solves the Internet Explorer limitation of loading not more then 30 CSS files per HTML page (http://support.microsoft.com/kb/262161). It is suitable for Drupal websites using lots of modules that can quickly increase the number of CSS files. The module doesn't require any configuration, just enable it and it will automatically change the way Drupal loads CSS files. It works well with built-in Drupal 6 CSS compression.
