I downloaded the Western US map for the Nokia Map application yesterday (2009.09.23) to my PC using the following link:

It took over 5 hours to download the 753 MB file. Slooow server.

When I had a failure to download OpenStreet map files to Maemo Mapper it turned out that I had somehow reset File Path (Menu > Settings) to the nearly full internal memory card, and the maps simply did not download.
