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 or in the selected module.

Note that Drupal’s CSS optimization (and this module) doesn’t work when files are transferred using Drupal 6’s private download method. SeeThis incompatibility is fixed in Drupal 7.
Drupal 7 version
At this time, it appears this module is not needed for Drupal 7. See
