Comment(by donncha):

 Adding the following line to the theme's functions.php enables it. With
 the image uploader icon missing the thumbnail uploader doesn't work,
 you're right. I guess because some Javascript is loaded or something.

 {{{
 add_theme_support( 'post-thumbnails' );
 }}}

 I may try the same theme support detection and switch on image uploads so
 the thumbnail works. Either that or display a warning to site admins when
 the thumbnail support is detected. That might be the best thing.
