If you upgraded, your hack is most probably lost. Just adding the radio button wouldn't help. Try asking the person who made the hack and see if there's a version of it, compatible with vB 3.5.4, and ask if you can get the code. If it's just the button that's missing, here's a sample code for a radio button.

PHP Code:

print_radio_row($vbphrase['auto_subscription_mode'], 'user[autosubscribe]', array(
    -1 => $vbphrase['subscribe_choice_none'],
    0  => $vbphrase['subscribe_choice_0'],
    1  => $vbphrase['subscribe_choice_1'],
    2  => $vbphrase['subscribe_choice_2'],
    3  => $vbphrase['subscribe_choice_3'],
), $user['autosubscribe'], 'smallfont');
