"Device is not power manageable"

And how does one identify that device?

I have posted a patch for that (2 times iirc) but it seems
to have been dropped/lost (I can't even find it in the email
archives).  It's at home, I can repost it tonight, but it's
fairly trivial:  just print something like dev->bus_id (just
guessing from not recent memory).  I'll send it tonight.

Here's the patch that I have used.

-- 

From: Jae-hyeon Park <jhpark@tuhep.phys.tohoku.ac.jp>

Identify which device is not power-manageable to make
the message more useful.

Thanks.  I guess that won't be very popular due to using linux-specific
stuff in a generic file, but I'll merge it.

That will conflict with latest patches:
ACPI_DEBUG_PRINT((ACPI_DB_WARN, ...)) have been converted to 
ACPI_WARNING((AE_INFO, ...)).

This was done because a lot real error/warning messages were only printed with
ACPI_DEBUG=y (like all ACPI_DEBUG_PRINT messages).

In this case I used ACPI_INFO((AE_INFO,...)) as I knew the message
pops up here and there.

This one lets the message vanish totally and only shows it with ACPI_DEBUG=y and 
acpi_dbg_level | ACPI_DEBUG_INFO:
