Comment (by homann):

 Again, the WKT you have supplied is not translated by OGR into the proj-
 string you think it should be. OGR library is used for that. The proj-
 string is then used by PROJ4 to do the actual projection. OGR library is
 used for that translataion also.

 If you use the GDAL/OGR program "testepsg <your-WKT-definition>" you will
 see that OGR does not pick up the datum. The error (if any) is
 reproducable outside QGIS. If you are sure the WKT is correct, please file
 a bug with OGR, where the problem (if any) can be solved.

 Posting more comments here will not fix the problem.
