I'm not concerned about (b).
I'm quite curious how you are planning to solve (a). I think it would
help move this conversation forward if you could take a couple acpi
tables in use today (eg, madt, srat) and describe the future format
and location for each field in those tables. I think it would also be
useful if you could do the same for a couple DSDT entries (eg,
\_SB.PCI0, \_SB.PCI0.ISA) and also describe how you plan to have the
guest build the AML from that info.
