The projection is available in QGIS 2.2 on Windows. Parameters are:

+proj=tmerc +lat_0=-90 +lon_0=-72 +k=1 +x_0=1500000 +y_0=0 +ellps=GRS80 
+towgs84=0,0,0,0,0,0,0 +units=m +no_defs

for Argentina 1. The others just have a different lon_0 and x_0.

So no problem with datums. +towgs84 is all zero, even for Posgar94 and 
Posgar 98. Posgar 98 and 2007 have identical paramaters, Posgar94 has 
WGS84 ellipsoid.
