-               Linux Power Management Support

-This document briefly describes how to use power management with your
-Linux system and how to add power management support to Linux drivers.

-APM or ACPI?

-If you have a relatively recent x86 mobile, desktop, or server system,
-odds are it supports either Advanced Power Management (APM) or
-Advanced Configuration and Power Interface (ACPI).  ACPI is the newer
-of the two technologies and puts power management in the hands of the
-operating system, allowing for more intelligent power management than

-build a kernel with both ACPI and APM enabled (as of 2.3.x ACPI is
-enabled by default).  If a working ACPI implementation is found, the
-ACPI driver will override and disable APM, otherwise the APM driver
-will be used.
-
-No, sorry, you cannot have both ACPI and APM enabled and running at
-once.  Some people with broken ACPI or broken APM implementations
-would like to use both to get a full set of working features, but you
-simply cannot mix and match the two.  Only one power management
-interface can be in control of the machine at once.  Think about it..

I'd keep this; it is still true, and we still support both.

Maybe it should be moved into Doc*/power/apm.txt or something.

Yes, if there is a good sub-directory for it, please put it there.

ACK on rest.

Updated patch is appended.

Thanks,
