[wp-hackers] Conditionals not working properly when trying to filter admin_footer_text

I'm trying to filter the admin footer text just for the Subscriber role 
using admin_footer_text.

I'm using conditionals to target Subscribers and version 3.2. The code 
I'm using is:


function my_custom_admin_footer_text() {
     global $blog, $blog_id, $current_user, $custom_footer_text, $id, 

     $custom_footer_text = '<span id="footer-thankyou">'.__('Powered by 
<a title="WordPress" href="http://wordpress.org/">WordPress</a>').'</span>';

     /* Let's change the footer text for Subscribers in WordPress 3.2 or 
higher */

     if ((!current_user_can('edit_posts') || 
!current_user_can_for_blog($blog_id, 'edit_posts')) && $wp_db_version >= 
18226) {
         echo $custom_footer_text;


add_filter('admin_footer_text', 'my_custom_admin_footer_text');


The results are:

- In version 3.1, for all roles, the footer text for every role is 
getting whacked completely, rather than displaying the default footer 
text from admin-footer.php. Conditional indicates db version is WP 3.2 
or higher, so 3.1 shouldn't get touched.

- In version 3.2, the footer text is being replaced for Subscribers, but 
is whacked completely for all other roles.

Is there an issue with using conditionals when trying to filter 
admin_footer_text? If not, any ideas on why the above code isn't 
functioning properly?

Thanks in advance.
