uninc,

I don't think that's the solution. For example, my DSDT has this (and I have no issue with brightness, either from sleep, or from the keyboard):

Code:

                       Method (_BCL, 0, NotSerialized)
                        {
                            Return (\_SB.PCI0.LBCL)
                        }

                        Method (_BCM, 1, NotSerialized)
                        {
                            \_SB.PCI0.LBCM (Arg0)
                        }

Is your brightness issue one of resuming from sleep, or are you just trying to adjust the brightness from the keyboard? Do you have a PS2 keyboard (typically your DSDT will have a Device (PS2K) entry)?

If the PS2 keyboard dimming, you could try adding the following to the PS2K device:

Code:

                    Method (_DSM, 4, NotSerialized)
                    {
                        Store (Package ()
                            {
                                // We are telling the system that we have FN keys
                                "AAPL,has-embedded-fn-keys",                                                                              
                                Buffer (0x04)
                                {
                                    0x01, 0x00, 0x00, 0x00
                                }                
                            }, Local0)
                            DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                            Return (Local0)
                    }
