lack of support for South African projections

South African Coordinate System zone xx (EPSG odd numbers from 22275 - 22293)
Hartebeesthoek94/ Loxx (EPSG 2046 - 2055)
are not supported / do not have standard definitions in proj4. South Africa users of proj4, QGIS, PostGIS and others are thus crippled.
Attached are the WKT and PROJ4 definitions as csv’s from PostGIS spatial_ref_sys.
SA Hartebeesthoek datum.csv:
4148 is fine - that's the fundamental GEOGCS. The rest have default, invalid proj4 definitions, except for 2054 (the last one) where I have attempted a proj4 definition but I don’t think it’s quite right - it doesn't work.
SA Cape datum.csv:
The proj4 definitions for the SA Cape datum projections are INCOMPLETE. They only include the datum specs, not the projection or central meridian or other parameters.
Apparently the problem is that proj4 does not support 'transverse_mercator_south_orientated'?
