According to http://instlatx64.atw.hu/ data (thanks to Radim!) NRIPSAVE apeared somewhere in Opteron_G3 lifetime (e.g. QuadCore AMD Opteron 2378 has is, QuadCore AMD Opteron HE 2344 doesn't), NPT was introduced a bit earlier. To be on the safe side we can probably add NPT and NRIPSAVE to Opteron_G4 and Opteron_G5 too and leave Opteron_G3 as it is. -- Vitaly
