What you need to find is the method that is called upon a lid switch event, which means it is under EC0, the embedded controller device. On a MacBook, it's typically _Q20, which looks like this:

Code:

                    Method (_Q20, 0, NotSerialized)
                    {
                        Store (LSTE, LIDS)
                        Notify (\_SB.LID0, 0x80)
                    }

On my Gateway, it's _Q8A:

Code:

                    Method (_Q8A, 0, NotSerialized)
                    {
                        If (LIDE)
                        {
                            Store ("_Q8A : LID Switch Event", Debug)
                            Store (0x01, LIDE)
                            If (IGDS)
                            {
                                Store (0x90, SMIF)
                                Store (0x00, TRP0)
                            }

                            Notify (\_SB.LID0, 0x80)
                        }

on many other notebooks, it's _Q09. So you'll need to find where it is, and add the appropriate Notify call, to inform the OS that the laptop should be woken up. (I've modified my DSDT to use LID0, to better match the MacBook DSDT).
