    It should be easy enough to enable it for AMD as well, and it would also be
    good to track down the one failure you found... I don't *think* the
    re-ordering of MTRR initialization should affect AMDs anymore than it does
    Intel, but someone familiar with the boot code would have to do a quick audit
    to be sure.
