Are you sure you have the data stored in AUX? ArcGIS Desktop uses an AUX
file for images that do not support storing coordinate system information
internally. The image header and AUX file tells ArcMap about the coordinate
system including units and projection.
It happens that AUX files are created also when ArcGIS produce image
pyramids.
I suggest to export your data in Arc/Info Binary Grid, a format easily
handled by GDAL [1] . In this case you have to point gdal to the "hdr.adf"
file (one of the many *.adf files produces while exportiong), which is the
header file.
