Markus, Yes, you probably need to insert a new definition ito pcs.csv / gcs.csv. I believe the CSV files in $(GDAL_ROOT)/data come from libgeotiff and are derived from the EPSG database. See the README in http://trac.osgeo.org/geotiff/browser/trunk/libgeotiff/csv
But if you don't want to hack those CSV files, maybe the simpler solution would be to specify your projection as a WKT string instead of an EPSG code. That way, GDAL wouldn't have to query the CSV files in order to build the WKT string (GDAL/OGR internal model for storing SRS is a tree based on WKT representation).
