add this function to template.php

function phptemplate_preprocess_node(&$vars) {
  // If we have any terms...
  if ($vars['node']->taxonomy) {
    // Let's iterate through each term.
    foreach ($vars['node']->taxonomy as $term) {
      // We will build a new array where there will be as many
      // nested arrays as there are vocabularies

      $vocabulary[$term->vid]['taxonomy_term_'. $term->tid]  = array(
        'title' => $term->name,
        'href' => taxonomy_term_path($term),

          'title' => strip_tags($term->description),
        ),
      );       
    }
    // Making sure vocabularies appear in the same order.
    ksort($vocabulary, SORT_NUMERIC);
    // We will get rid of the old $terms variable.
    unset($vars['terms']);
