I have made some simple changes to the node module to allow you to mass/select/delete nodes from the admin/content page. I know its pretty basic, but I needed it...so here it is.

Change:

  $operations = array(
    array(t('Approve the selected posts'), 'UPDATE {node} SET status = 1, moderate = 0 WHERE nid = %d'),
    array(t('Promote the selected posts'), 'UPDATE {node} SET status = 1, promote = 1 WHERE nid = %d'),
    array(t('Make the selected posts sticky'), 'UPDATE {node} SET status = 1, sticky = 1 WHERE nid = %d'),
    array(t('Demote the selected posts'), 'UPDATE {node} SET promote = 0 WHERE nid = %d'),
    array(t('Unpublish the selected posts'), 'UPDATE {node} SET status = 0 WHERE nid = %d'),
  );

to this:

  $operations = array(
    array(t('Approve the selected posts'), 'UPDATE {node} SET status = 1, moderate = 0 WHERE nid = %d'),
    array(t('Promote the selected posts'), 'UPDATE {node} SET status = 1, promote = 1 WHERE nid = %d'),
    array(t('Make the selected posts sticky'), 'UPDATE {node} SET status = 1, sticky = 1 WHERE nid = %d'),
    array(t('Demote the selected posts'), 'UPDATE {node} SET promote = 0 WHERE nid = %d'),
    array(t('Unpublish the selected posts'), 'UPDATE {node} SET status = 0 WHERE nid = %d'),
    array(t('Delete the selected posts'), 'delete from {node} WHERE nid = %d')
  );
