------- Comment #61 from ming.m....@intel.com  2008-12-11 19:48 -------
void __init acpi_early_init(void)
         .....
         status = acpi_ec_ecdt_probe();
         /* Ignore result. Not having an ECDT is not fatal. */

         status = acpi_initialize_objects(ACPI_FULL_INITIALIZATION);
         .....
}

acpi_ec_ecdt_probe -> ec_install_handlers -> acpi_install_address_space_handler
-> acpi_ev_execute_reg_methods -> _REG method is called

acpi_initialize_objects -> acpi_ns_initialize_devices ->
-> acpi_ns_init_one_device -> _INI method is called

This is why _REG method is called before _INI method.
