You are right, the projection name is not known for QGIS.

The WKT string for Kertau RSO is:


PROJCS["Kertau (RSO) / RSO Malaya (m)",
     GEOGCS["Kertau (RSO)",
         DATUM["Kertau_RSO",
             SPHEROID["Everest 1830 (RSO 1969)",6377295.664,300.8017,
                 AUTHORITY["EPSG","7056"]],
             AUTHORITY["EPSG","6751"]],
         PRIMEM["Greenwich",0,
             AUTHORITY["EPSG","8901"]],
         UNIT["degree",0.0174532925199433,
             AUTHORITY["EPSG","9122"]],
         AUTHORITY["EPSG","4751"]],
     PROJECTION["Hotine_Oblique_Mercator"],
     PARAMETER["latitude_of_center",4],
     PARAMETER["longitude_of_center",102.25],
     PARAMETER["azimuth",323.0257905],
     PARAMETER["rectified_grid_angle",323.1301023611111],
     PARAMETER["scale_factor",0.99984],
     PARAMETER["false_easting",804670.24],
     PARAMETER["false_northing",0],
     UNIT["metre",1,
         AUTHORITY["EPSG","9001"]],
     AXIS["Easting",EAST],
     AXIS["Northing",NORTH],
     AUTHORITY["EPSG","3168"]]

which looks similar to the one given, but the ellipsoid major axis is 
different, and False Easting.

For the different namings of the projection, see
