Code: 
AddHandler application/x-httpd-php .css (EDIT: This breaks CSS on version 2.3.x)
php_value auto_prepend_file gzip-css.php
php_flag zlib.output_compression On
This code does 3 things:

1 - The first line tells Apache to send all .css files to the PHP script handler.
2 - The second line prepends the code snippet to your CSS file.
3 - Optional: The third line tells PHP to use its built-in negotiated output compression automatically for every page it parses. If you use this method for compression, there is no need for having ob_start ("ob_gzhandler"); in the code snippet. So choose one or method or the other...

In addition, some hosts do not allow (or like) persistant connections being enabled. If you are contacted by your host for resource consumption and/or your board is slowed down after following this tutorial - please disable persistant connections FIRST.
