DSDT for EEE PC 901

I am running a 900A, but this should work on the 901 as well.

Patch DSDT yourself - extract the table using fassls Patcher and open dsdt.dsl

Add this code after "Scope (_SB)" section - paste after those lines starting with "Alias (PRSA, ****)":

Device (PNLF)
{
  Name (_HID, EisaId ("APP0002"))
  Name (_CID, "backlight")
  Name (_UID, 0x0A)
  Name (_STA, 0x0B)
}

Add this:

Method (WAK, 1, NotSerialized)
{
   \_SB.PCI0.SBRG.EC0.EC0W (Arg0)
   \_SB.PCI0.NWAK (Arg0)
   \_SB.PCI0.SBRG.SWAK (Arg0)
   LPWK (Arg0)
   Store(\_SB.ATKD.PBLG(),local0)
   \_SB.ATKD.PBLS(local0)
}

Display Brightness & LID Sleep issues are fixed now, but in case of my 900A this breaks Shutdown. So I removed EvOReboot.kext and used the shutdown fix neron had posted here (appl elife.ru/topic/21865-%D0%BF%D1%80%D0%B0%D0%BA%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8%D0%B5-%D0%BF%D1%80%D0%B8%D0%B5%D0%BC%D1%8B-%D0%BF%D0%BE-%D1%80%D0%B5%D0%B4%D0%B0%D0%BA%D1%82%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E-dsdt-%D1%87%D0%B0%D1%81%D1%82%D1%8C-2/page__st__480__p__176307#entry176307):

    Method (_PTS, 1, NotSerialized)
    {
        If (LEqual (Arg0, 0x05)) {}
        Else
        {
            all code previously placed in _PTS,1 section
        }
    }

Save dsdt.dsl and assemble using iasl -ta

Have Fun. :
