This _OS stuff is pure crasp IMHO.  The _OSI method is a Microsoft
extension, and is documented somewhere in their site.  As for
_OS, that is only crasp.

Note that you can pass the acpi_os_name='' if you want
to change _OS so that some method may work 'better' for you.
Sometimes, it may help to try others values, but YMMV.


Note also that only some thinkpads have _OS == 'Linux' related
stuff implemented in their DSDT, but it seems that it is not
well used though (at least, IBM do care of that, even
if it is not perfect).
I don't find that others vendors do care of others OS other
than redmond' one.  But it is for laptops/desktop word.

To be fair, _OS seems not to be used in servers.
