_OSI and _OS DSDT methods

[Huw Rogers <count0-tC47gz4GrgtWk0Htik3J/w@public.gmane.org>]

The _OSI method is used in my DSDT in addition to the OS name returned
by the _OS method (http://www.microsoft.com/whdc/hwdev/tech/onnow/_OSI-method.mspx).

The results influence the behaviour of many other methods in the DSDT,
including sleep/wake methods. This OSFL() method is called and if/else
blocks depend on the return value:

Name (OSVR, Ones)
Method (OSFL, 0, NotSerialized) {
    If (LNot (LEqual (OSVR, Ones))) {
	Return (OSVR)
    }

    Store (0x01, OSVR)
    If (MCTH (\_OS, "Microsoft Windows NT")) {
	If (LEqual (OSVR, 0x01)) {
	    If (CondRefOf (_OSI, Local0)) {
		If (\_OSI ("Windows 2001")) {
		    Store (0x04, OSVR)
		}
	    } Else {
		Store (0x00, OSVR)
	    }
	}
    } Else {
	If (MCTH (\_OS, "Microsoft WindowsME: Millennium Edition")) {
	    Store (0x02, OSVR)
	}
    }

    Return (OSVR)
}


What should Linux return for _OS and _OSI? Should 2.6 mimic Windows XP?
Does it?
