Currently, in views_plugin_style.inc, when a "grouping field" is enabled, rendered groups are simply concatenated with no theme.
See line 159:

<?php
  $output .= theme($this->theme_functions(), $this->view, $this->options, $rows, $title);
?>

There should be some better theming support.

I'm quite sure that there exist an issue for 6.x-3.x already with some kind of patch which allows to have multiple layers of grouping as well, sadly it's impossible to find it at the moment.
