the concern here is that the mttr values are different
on the 2 processors so they are seeing different memory
attributes for those ranges (the warning messages are
only printed if there is an inconsistency).
depends what's mapped at those addresses. i7 is likely
an apic or somesuch and shouldn't be a problem. i6 is
just below 512MB physical and might be a problem depending
on how much memory is in the machine; the e820 map
would be useful here, maybe it's some acpi thing.
"fixing" the mttrs as in making them consistent would be
a pain.
