IE bug

Internet Explorer will refuse to load more than 31 linked stylesheets. Unfortunately, the alternative to load styles using @import statements (which Drupal 5 used), has bad performance implications.

The fix for this on production sites is to simply enable the Optimize CSS files option on admin/settings/performance. Unfortunately, that option makes developing CSS for themes or modules a true PITA. This module adds a developer-friendly solution to the Optimize CSS files feature; it aggregates all stylesheets except for those in the theme.

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.
