LOAD/STORE have lots of advantages (I have detailed some in Allow me to make a remark here: where does that leave people with older *mainboards with embedded NCR chips* ? Might be not too interesting for Intel folks, but most likely *is* for the Alpha folks. Mind you, I have not checked this on my Alphas (and the one Intel with embedded ncr) but I have a *bad* feeling over it as they are older stuff. The 'lets throw away the old hardware' that reigns the Intel world is less applicable to the Alpha world. A driver that cannot accomodate older hardware is a step in the wrong direction here.
