Right, for the case of platform-configured memory. Len, I'm wondering
if there is any reasonable way we can get memory-map-related stuff out
of ACPI before we initialize the full ACPICA... we could of course write
an ad hoc static parser (these are just static tables, after all), but
I'm not sure if that fits into your overall view of how the subsystem
should work?
