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).
Best regards,
Even
