thanks for the answer, so far I was able to unpack the windows ".exe" files
with 7z and get directly at the needed *.img files.

In any case the *.img format is described here 
  http://wiki.openstreetmap.org/wiki/OSM_Map_On_Garmin/IMG_File_Format
including the mention of the tre+rgn+lbl subfiles and it looks like it
should be one of the easier programming tasks to build the image.
