And there's also the whole different dataset HAEDARLIKAN_LMI which
contains an img and a 1 gig ige file, but it looks like they're not
supported by gdal.
You are right that the .ige file is not supported, but take the .img and
you get the DEM data you want:
gdalinfo haedarlikan__LMI__isn93.img
Driver: HFA/Erdas Imagine Images (.img)
Files: haedarlikan__LMI_isn93.img
haedarlikan__LMI_isn93.img.aux.xml
haedarlikan__LMI_isn93.ige
haedarlikan__LMI_isn93.rrd
