I'm afraid I know very little of the subtleties of Erdas overviews, but I see 
that the HFA_USE_RRD config option can also be set to YES and produces a .rrd 
file. Perhaps this is was you are looking for.  See 
http://gdal.org/frmt_hfa.html . I've found also a past thread where this is 
somehow discussed : http://www.mail-archive.com/gdal-
