This issue is a real tough one to troubleshoot remotely; you're going to have to play around with it. Read my post for questions about point 2 and 5; read this for details on point 4.

Make sure you have:
1. ACPIBacklight.kext loaded (run 'kextstat' and run 'grep ACPIBacklight /var/log/system.log')
2. All four ACPI methods in your PNLF Device (_BQC, _BCL, _BCM _DOS)
3. You've given a EisaId to your LCD Device
4. You have all the HasPanel, Haslid, backlight-control, boot-display and built-in properties set in your _DSM of your graphics device
5. You have the four lines in your _WAK
6. You have your OperationRegions set
See my post (#68) for your "only works from lowest to middle", your levels probably need tweaking. I don't know of a good way to find the true upper limit besides trial/error. Mine ended up being 1600 decimal (0x0640)
