I just learned that two very nice sets of old, out-of-copyright Swedish maps have been made freely available. Maybe they have already been around for a while, but I just learned this now. One set is the topographic map (popularly called Generalstabskartan) in scale 1:100,000 for southern and 1:200,000 for northern Sweden. The other is the economic map (Häradskartor) in more detail.
These maps have long ago been digitized by the Swedish ordnance survey (Lantmäteriet), but they don't allow downloading and reuse. Now, however, they have been (digitized again? and) made freely available by Stockholm University library, http://kartavdelningen.sub.su.se/kartrummet/kartskapet.htm
The maps are scanned in 600 dpi and are available in TIFF and JPEG. Some have also been geo referenced and have TFW and KML files for download.
Can we somehow get these huge bitmap images into a tileserver? They need of course be stretched to fit the coordinates, and the borders and overlaps need to be aligned. What tools are available for that? Would WMF support and host this? Would OSM? If someone can do this for a fee, maybe the Swedish chapter can find the money.
Just upload to commons. There is a Gadget "ZoomViewer" which uses the toolserver to generate multiresolution pyramids (like tiles) and display it using either flash [1] or JavaScript [2]. Daniel

Stockholm University already provides a Flash-based zoomer. What I wanted to achieve was the ability to link to a coordinate, as part of an OpenStreetMap layer, from Wikipedia articles that have coordinates.

This is part one of your question. Find out how if the zoomify viewer of Stockholm university supports link parameters, that zoom and pan to a specific location.

Huh?! Where does the OpenStreetMapLayer come into play here?! I don't see that.
Here is a suggestion: GoogleEarth supports tile-based overlays through KML files. This is the closest thing to what I think you want to do (overlay the old maps over new cartographic material). I don't see this happening in OSM though. Daniel

What I remembered was http://www.npemap.org.uk/ where old British NPE maps have been scanned and stitched together in a zoomable web interface. In my dreams, this was based on OpenLayers, but in reality this website turns out to be a more primitive solution.
But perhaps I'm not so mistaken after all. From the article http://en.wikipedia.org/wiki/Leeds if I click the coordinate in the upper left, I arrive at http://toolserver.org/~geohack/geohack.php?pagename=Leeds%C2%B6ms=53_47_59_N... where one of the alternatives is "Ordnance Survey NPE 1:50000 (England / Wales), 1945-1955 (via OpenStreetMap)", http://ooc.openstreetmap.org/?zoom=15&lat=53.799722&lon=-1.549167&am...
OOC stands for out-of-copyright maps, so this is where I should go. Maybe this only concerns OSM and not WMF at all? I think WMF with all its cooperations with libraries and other cultural institutions could help to liberate more old maps for OpenStreetMap.
There is a similar project using maps from the British ordnance survey [1]. Try asking on the OpenStreetMap talk-gb list [2] or ask Firefishy [3] who is one of the OSM sys-admins and I think he is also responsible for hosting the British OS maps.
There is also a project on the Wikimedia Toolserver [4] for hosting a OSM tile server - I don't know much about it, but you might also be able to host it there.
