I know... that's why am I asking... If I could get to OEA, I could activate altivec instruction set, and then by small hack enable it in the dnet client... I suppose, it's really worth... imo dnet client doesn't check for OS 1.5, but only for AltiVec enabled... and fon't forget, that if there will be only dnet client using altivec, then OS doesn't have to care about it's registers and so, as nothing else will operate with them...
