In order to minimize required special handling for running as Xen PV

NVS is located at 64 MB, resulting in a conflict with the loaded
kernel or the initial page tables built by Xen.
As ACPI NVS needs to be accessed by the kernel only for saving and
restoring it across suspend operations, it can be relocated in the
dom0's memory map by swapping it with unused RAM (this is possible
via modification of the dom0 P2M map).
Shouldn't this paragraph be amended / re-written, as this was what made
me ask for what is now patch 6?
