Ingo Molnar 1e22436eba x86: reserve low 64K on AMI and Phoenix BIOS boxen 
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.
