In my efiemu I have a code which does exactly the opposite. But 
additionally it allows the user to replace/add/remove ACPI tables. 
Perhaps we can share the code and make it also works in cases like 
replacing some of ACPI tables on pc then putting new rsdp pointer to 
EBDA, replacing some tables on efi system then using EBDA, modyfiing 
acpi on efi and putting bew rsdp back to efi and so on.
