Has there been any luck with this?

I came across this page hoping to get the ENC raster images into Maemo Mapper on my n810.

Something tells me it isn't as simple as taking rasters, assigning zoom levels to them and giving them 2 corners (lat/long of northwest corner, lat/long of southeast corner) but it seems like it ought to be that simple. Can anyone explain how far off I am and if there are any resources for how to create a new map repository?
