It is true that the driver doesn't write automatically the GEOLOB TRE, but you can manually do it by using the TRE creation option of the NITF driver. See http://gdal.org/frmt_nitf.html and http://gdal.org/frmt_nitf_advanced.html. This will require you to format it "at hand" properly from the georeferencing info. But you should also likely write the GEOPSB TRE, so that the resulting NITF file is valid in a non GDAL based NITF reader. I've found some more info here about those TREs : http://www.gwg.nga.mil/ntb/baseline/docs/stdi0006/NCDRD_20Dec06.pdf and http://www.ittvis.com/portals/0/pdfs/envi/NITF_Module.pdf.
