    x86: reserve low 64K on AMI and Phoenix BIOS boxen · 1e22436e

    there's multiple reports about suspend/resume related low memory
    corruption in this bugzilla:
    
      http://bugzilla.kernel.org/show_bug.cgi?id=11237
    
    the common pattern is that the corruption is caused by the BIOS,
    and that it affects some portion of the first 64K of physical RAM.
    
    So add a DMI quirk
    
    This will waste 64K RAM on 'good' systems too, but without knowing
    the exact nature of this BIOS memory corruption this is the safest
    approach.
    
    This might as well solve a wide range of suspend/resume breakages
    under Linux.
