ACPI Sleep gone in 2.5.66? And is my Bios Windows only?

[Malte Doersam <malte.d-hi6Y0CQ0nG0@public.gmane.org>]

Hi everybody,

I have a Thinkpad R31 which has some really annoying APM bugs, so I just tried 
ACPI:

Using 2.4.21-pre3 [1] I got almost everything working when I used pci=noacpi 
as a kernel argument. Even Sleep worked, though the onboard e100 didn't wake 
up. (Using the Intel driver or the "original" kernel driver didn't matter.) 
Here is my dmesg [2] and my dsdt [3].

I tried 2.5.66 [4] and hoped, that the pci=noacpi would not be necessary 
anymore. But all of a sudden the /proc/acpi/sleep isn't there anymore, which 
is pitty. My dmesg [5] and my dsdt [6] for 2.5.66.

I modified my DSDT as described here:

What I asked myself, studying my DSDT: could it be, that certain features only 
work with MS operating systems?

        If (LEqual (Arg0, 0x04))
        {
            If (OSCP (\_OS, "Microsoft Windows"))
            {
                Store (0x00, OSTP)
            }
            Else
            {
                If (OSCP (\_OS, "Microsoft Windows NT"))
                {
                    Store (0x01, OSTP)
                }
                Else
                {
                    If (OSCP (\_OS, "Microsoft WindowsME: Millennium 
Edition"))
                    {
                        Store (0x02, OSTP)
                    }
                    Else
                    {
                        Store (0x07, OSTP)
                    }
                }
            }
--snap--

So I tried modifying the Else to Store (0x00, OSTP) but it didn't change 
anything.


Questions over questions, maybe someone can bring some light into this... :-)

cheers Malte
