    Whooooowww... Power4 I believe opted out at 16MB.
    So the story about sleeping beauty is true :-).

    Wouldn't want to manage the 8-32 physical pages of memory through the VM.
    Paging not an option, file access irrelevant.

    In that case I agree that it should be handled by a special purpose
    extension like Seth's patch to cover a 4GB page.

    Upto 4MB or so I still believe going the other way is proper.
    More later... thanks for the info.
