Hi,

I was just trying to get my sleep button to work, not that swsusp has
gone gold. I've got three buttons, which are controlled by acpi; Sleep,
Soft power and Lid. Kernel gives @ bootup;

ACPI: AC Adapter [AC] (on-line)
ACPI: Battery Slot [BAT0] (battery present)
ACPI: Power Button (FF) [PWRF]
ACPI: Sleep Button (FF) [SLPF]
ACPI: Lid Switch [LID]
ACPI: Processor [CPU0] (supports C1 C2, 8 throttling states)
ACPI: Thermal Zone [THRM] (59 C)

Which seems to indicate fixed-featue buttons. I've set up acpid like this;

------
event=button/lid LID.*
action=logger ACPI lid %e
------
event=button/power PWRF.*
action=logger ACPI power %e
------
event=button/sleep SLPF.*
action=logger ACPI sleep %e
------

Which makes Lid and Soft Power worky, but, alas, Sleep is noworky. I get
no events whatsoever:(. Note, though, I've yet to see any docs of how to 
setup acpid, so I'm just assuming this is right.

DSDT gives this;

Scope (_SB)
    {
        Device (SLPB)
        {
            Name (_HID, EisaId ("PNP0C0E"))
            Name (_PRW, Package (0x02)
            {
                0x01,
                0x03
            })
        }

        Device (PWRB)
        {
            Name (_HID, EisaId ("PNP0C0C"))
            Name (_PRW, Package (0x02)
            {
                0x01,
                0x04
            })
        }

        Device (LID)
        {
            Name (_HID, EisaId ("PNP0C0D"))
            Name (_PRW, Package (0x02)
            {
                0x01,
                0x03
            })
            Method (_LID, 0, NotSerialized)
            {
                If (\_SB.PCI0.ISA.EC.ECOK)
                {
                    If (\_SB.PCI0.ISA.EC.LIDS)
                    {
                        Return (0x00)
                    }
                    Else
                    {
                        Return (0x01)
                    }
                }
                Else
                {
                    Return (0x00)
                }
            }
        }


I'm not sure where I go from here. Is this a bug, perhaps? I've
tried to see if the buttons generate and scancodes, but they don't. So I
assume they're indeed controlled by acpi directly. Cheers,

/Chris
