Upgrading to dev version breaks theme_gmap

I just upgraded to 6.x.1.x-dev in order to fix the problem described in this issue: http://drupal.org/node/662390

Now the code in my theme doesn't work when I call theme('gmap' ...). I get the "Javascript is required to view this map" error. Strangely, the map that I'm using directly from views (no PHP code) works fine. I've compared the gmap javascript files on both of those pages and they appear to be the same. So, what's the problem? I'm stumped.

Here's the code that I can't get to work:

<?php
$behvr = array('autozoom');
                        $markers = array(
                            array(
                                'longitude' => $node->location['longitude'],
                                'latitude' => $node->location['latitude'],
                                'text' => $node->title
                              )
                        );
                        
                        $map_array = array(
                            'id' => "farm-map",         // id attribute for the map
                            'width' => "250px",        // map width in pixels or %
                            'height' => "250px",      // map height in pixels
                            'latitude' => $node->location['latitude'],    // map center latitude
                            'longitude' =>$node->location['longitude'],  // map center longitude
                            'zoom' => 12,              // zoom level
                            'maxzoom' => 15,
                            'maptype' => "Satellite",       // baselayer type
                            'controltype' => "Small",  // size of map controls
                            'markers' => $markers,

                          );
                          gmap_gmap('pre_theme_map',$map_array);
                          $output1 = theme('gmap', array('#settings' => $map_array));
                          echo $output1;
?>

I've also tried making this work with views_embed_view but that won't do it either.
