I think this code should be:

if ((obj->Package.Elements[element].Type  != ACPI_TYPE_BUFFER) && 
(obj->Package.Elements[element].Type  != ACPI_TYPE_INTEGER)) {

and from the spec 8.4.5.1,
the type should be buffer:
method_test_type_buffer  (fw, &failed, obj, 13, "NominalCounterRegister");
method_test_type_buffer  (fw, &failed, obj, 14, "DeliveredCounterRegister");
method_test_type_buffer  (fw, &failed, obj, 15, 
"PerformanceLimitedRegister");
method_test_type_buffer  (fw, &failed, obj, 16, "EnableRegister");
