Was DEC Alpha an Open Source project? ;-)
Memory barriers are more RISC-styled and more flexible anyway (e.g. you
can't run out of them ;-) ), though they require a greater care when
writing code. MTRRs are the Intel style of complicating designs. Still
they are probably a reasonable solution to preserve DOS compatibility.
