from menu-header.php:
if ( 'div' === $item[6] )
   $img = '<div class="wp-menu-image"><br /></div>';
else
   $img = '<img class="wp-menu-image" src="' . $item[6] . '" alt="" />';

So, either you're passing a full img src and it outputs a regular
<img>, or you're passing 'div' and it outputs the <div> shown on line
2 of the snippet.

Example:
add_menu_page('page_title', 'menu_title', 'manage_options', 'blah',
'some_function', 'div');

This will add:
<li id="toplevel_page_blah" class="[various classes...]">
<div class="wp-menu-image"><br/></div>
[the link and stuff to the page...]
</li>

So you can style with something like:
#toplevel_page_blah div.wp-menu-image {
  background:transparent url(full url to icon);
}

In other words: mostly complicated compared to the regular & simple:
add_menu_page('page_title', 'menu_title', 'manage_options', 'blah',
'some_function', [full url to icon]);
