I recommend skipping WMI on IA64 unless/until a real need to support it emerges.
There are no WMI extensions on the Intel Tiger or Hitachi Fusion IA64 boxes I have access to.

Ok. The only other vendors I really have in mind are HP and Fujitsu, since 
both those vendors use WMI on their laptops, so they would be my most likely 
candidates to have WMI on an IA64 box (if anyone actually does use WMI on 
IA64).

Len:

You can either add a 'depends on X86' to WMI when you apply patch #1 from the 
second WMI series; or I can send another patch out later on top of this 
series to do this, once you replace the old patches in acpi-test - whichever 
is easiest for you)

How could I tell whether our HP systems use WMI?

Do you have any PNP0C14 or *pnp0c14 _HID objects defined in the DSDTs for your 
systems? If not, then your systems don't use WMI.

I looked at DSDTs for a few HP ia64 systems (rx7620,
rx8640, and superdome), and none has a PNP0C14 object.
