1. A system for accessing an Advanced Configuration and Power Interface (ACPI) namespace nodal tree in a computer platform employing an ACPI-compatible implementation, comprising: a namespace data structure operably associated with said computer platform, said namespace data structure having said ACPI namespace nodal tree with at least one node; an index data structure operably associated with said computer platform, said index data structure including at least one pointer pointing to an index node that spans a sub-tree of said ACPI namespace nodal tree, wherein said sub-tree includes said at least one node; and a traversing function operable to commence a searching operation for said at least one node in said sub-tree of said ACPI namespace nodal tree, wherein said traversing function commences said searching operation from said index node.
