[support] omega theme: preprocess html, AFTER media-size specific styles?

Hello!

Having this issue that the omega theme adds the size-specific CSS *after* any drupal_add_css I add to my THEME_preprocess_html

My syntax is:

drupal_add_css(path_to_theme() . '/css/ie-6.css', array('group' => CSS_THEME, 'browsers' => array('IE' => 'IE 6', '!IE' => FALSE), 'preprocess' => FALSE));

I want to make sure this is the very last CSS added, other than having the HTMLtpl.php directly, how can I get it to be really last, after the Alpha+Omega theme?

Please note I also tried adding "weight" of 9999 and -9999 but neither direction helps any, the conditional sheets always appear last in the chain and I want to add to the bottom of that list.

Thanks!

Sebastian
