PGeo driver fails to open .mdb due to limited size of the header

Description

Gdal 1.9 fails to open Esri Personal geodatabase file (.mdb) in some cases. The new PGeo driver looks into the header of the file for the GDB_GeomColumns table (http://trac.osgeo.org/gdal/changeset/21550) and cannot find it due to (I assume) the limited size of the header allocated (100Kbytes). My geodatabase has hundreds of tables and my assumption is that the buffer allocated for the buffer is too small to contain all the information required to check if the table exists.
