BIOS _OSI(Linux) query ignored on PRIMEQUEST

[Taku Izumi <izumi.taku@jp.fujitsu.com>]

Hi all,

The following message is displayed on our server(PRIMEQUEST):

  ACPI: bus type pci registered
  ACPI: EC: Look up EC in DSDT
  ACPI: BIOS _OSI(Linux) query ignored
  ACPI: DMI System Vendor: <NULL>
  ACPI: DMI Product Name: <NULL>
  ACPI: DMI Product Version: <NULL>
  ACPI: DMI Board Name: <NULL>
  ACPI: DMI BIOS Vendor: FUJITSU LIMITED
  ACPI: DMI BIOS Date: 1/17/2008
  ACPI: Please send DMI info above to linux-acpi@vger.kernel.org
  ACPI: If "acpi_osi=Linux" works better, please notify
linux-acpi@vger.kernel.org

Because "acpi_osi=Linux" boot option works well, so we want to
use _OSI(Linux) query on PRIMEQUEST without this boot option and
inihibit above message.

I thought the way to achive our goal was to add
the following entry to acpi_osi_dmi_table
(at drivers/acpi/blacklist.c),

   {
     .callback = dmi_enable_osi_linux,
     .ident = "Fujitsu PRIMEQUEST",
     .matches = {
             DMI_MATCH(DMI_BIOS_VENDOR, "FUJITSU LIMITED"),
	    },
   }

but unfortunately this table seems to be valid only for x86 machines.
Our server is ia64, but what is the best solution?
