Code

function dashboard_form_block_admin_display_form_alter(&$form, &$form_state, $form_id) {

  // Hide dashboard regions (and any blocks placed within them) from the block
  // administration form and from the options list on that form. This
  // function is called for both the dashboard block configuration form and the
  // standard block configuration form so that both forms can share the same
  // constructor. As a result the form_id must be checked.

      // administration form, so that they are available to place in other
      // regions of the theme. Note that when the form is submitted, any such
      // blocks which still remain disabled will immediately be put back in the
      // 'dashboard_inactive' region, because dashboard_block_info_alter() is
      // called when the blocks are rehashed. Fortunately, this is the exact
      // behavior we want.
