John, The windows binaries do not support MrSid. I recommend installing GDAL utilities from FWtools or OSGEO4W (which I think include MrSid support) and then using gdal_translate to convert your sid's to geotiffs.
You may want to pass the -co compression options to keep the size down. Rendering from GeoTiff will be much faster than sid as well. Also, in the next mapnik release raster reading with the GDAL plugin will be __much__ faster overall because of new support for Overviews.
