Comment (by pagesimplify):

 Not sure if it's counterproductive to add code changes here. I was about
 to submit this as a ticket until I saw this reported. Slap me on the hand
 as a first time offender if I'm going about this wrong.

 References apply to WordPress 3.3.1

 '''Change 1:''' Replace line with call to base class method using
 'themes_per_page'.
 Modify File: /wp-admin/includes/class-wp-themes-list-table.php

 Replace line 50 seen below:

 {{{
                 $per_page = 24;
 }}}

 With the following line:

 {{{
                 $per_page = $this->get_items_per_page( 'themes_per_page',
 24 );
 }}}

 This is consistent with the prepare_items() functions used in:
  - Plugins: /wp-admin/includes/class-wp-plugins-list-table.php
  - MS Themes: /wp-admin/includes/class-wp-ms-themes-list-table.php

 '''Change 2:''' Add Screen Options for themes_per_page for non network
 installation.
 Modify File: /wp-admin/themes.php

 Replace line 69 seen below:

 {{{
 add_thickbox();
 }}}

 With the following lines:

 {{{
 add_thickbox();
 add_screen_option( 'per_page', array('label' => _x( 'Themes', 'themes per
 page (screen options)' ), 'default' => 24 ) );
 }}}

 '''Change 3:''' Handle post back for saving themes per page.
 Modify File: /wp-admin/includes/misc.php

 Replace line 350 seen below:

 {{{
                         case 'plugins_per_page':
 }}}

 With the following lines:

 {{{
                         case 'plugins_per_page':
                         case 'themes_per_page':
 }}}

 '''Final Note:'''
 By implementing this modification, the following filter will effectively
 be called:

 {{{
         apply_filters( 'themes_per_page', $per_page );
 }}}

 From class WP_List_Table
 {{{
         function get_items_per_page( $option, $default = 20 )
 }}}

 in the file: /wp-admin/includes/class-wp-list-table.php
