Of the 889 ways in the file, 12 aren't tagged with a name. I've just
added support for the rendering of names to the map, so if you turn on
the ways layer and zoom in, you should be able to see it.

I obviously don't recognize it either way ;)

* Convert .osm to GML:
  http://wiki.openstreetmap.org/index.php/Converting_OSM_to_GML
  (This step is completed for you via
  http://london.freemap.in/output/planet_simple.gml.gz , 16MB download.)
* Convert GML to Shapefile:
  ogr2ogr -f "ESRI Shapefile" planet.shp planet.gml
* Set up mapserver with a mapfile pointing to your newly generated
  shapefile:
   http://wiki.openstreetmap.org/index.php/Displaying_OSM_Shapefiles_In_Mapserver
  is an example mapfile.

Of course, if you just want to display it in OpenLayers, you can use the
WMS that's already set up for the May Planet dump by copy pasting the
layer definition from the HTML file at
http://london.freemap.in/planetosm.html: 

var osm_wms = new OpenLayers.Layer.WMS( "OpenStreetMap Streets",
    "http://boston.freemap.in/cgi-bin/mapserv?map=/www/freemap.in/london/map/osm.map",
    {layers: "default_segment,segments,class_segment",
     transparent: "true", format: "image/png" });

It's my plan to keep the dataset powering that URL up to date with the
latest planet at all times.
