So ogr2ogr could convert them to geotiff that Xastir could handle?
That might be about the best option.  Actually, if they could be
converted to a standard image file with a .geo, then people could
handle them with ImageMagick alone, skipping
libproj/libgeotiff/libgdal support.  Possible?  It seems that if
they are a constant lat/long shift per pixel, we could do that.
