Hi Andy,

I should have given more details. We decided to add this extra parameter in AcpiLoadTable and
we're going to create an AcpiUnloadTable function that will take table index to unload the table (basically the acpi_tb_unload..).
Once we do this, you can use table indices with AcpiUnloadTable and AcpiLoadTable.
