As I did, you are trying to georeference subdataset 1. This is NOT
image band 1. This is the metadata and GCP's for image bands 1-3 VNIR.
So, now I understand my frustrations!
To actually georeference image band 1, you need to indicate
subdataset 2. The relationship between images and subdatasets is listed
at the bottom of the output to gdal-info. In brief, it is
> band 1=subdataset 2, 2=3, 3n=4, 3b=5, 4=8, 5=9, 6=10, 7=11, 8=12,
> 9=13, 10=16, 11=17, 12=18, 13=19, 14=20. Subdatasets 1, 5, 6, 7, 14,

This I think will be helpfull for many people since L1A data are more
frequent in ASTER database (as I remember 2 years ago L1B was realy rare.).

For MODIS not, but for ASTER 1A I can send you some outputs in monday if
you wisch. I Have not MODIS data in this moment.

It will be great too I think!
