This is the linux part.  It permit to pass a apci_os_name= boot args
in order to override the \_OS.

I'm still not clear on why this needs to be changeable at runtime. If we do
decide that the BIOS writers are so Windows-centric that we need to
masquerade as one, why wouldn't we just change the #define and recompile?

Dave, can you help me understand how a distro would find this useful, over
just statically changing the reported _OS string?

I can not speak for Dave, but suppose that you say to an end user:
Hum, yes, your mouse do not work after S1..

Get the latest kernel of the distro via apt-get, rpm, what ever, then
edit the file /path/to/kernel/include/acpi/platform/aclinux.h

find the
#define ACPI_OS_NAME                "Linux"
line then change so that
#define ACPI_OS_NAME                "Microsoft Windows NT"

recompile, etc.

Now suppose that you said to the same end user:
Add acpi_os_name="Microsoft Windows NT" at boot time, and now
your mouse will work without any tricks after S1 and with gpm
or under X.


Now, I don't like the idea to have a 
include/acpi/platform/aclinux.h
which say that my OS is a MS one, and I guess nobody want it.
