Actually, we should masquerade properly as the latest Windows version
available for that machine, then.  AFAIK, Windows does not set ALL the OSI
strings, just one.  We ARE running untested code in some BIOSes because of
it.

Maybe it would be better if every ACPICA-using OS defined a
_OSI(NotWindows), plus the relevant Windows OSI string they want to support,
and Intel would send word that this string is to be used ONLY to disable all
Windows bug workarounds, not to activate or deactivate any specific
functionality?
