Have you read the *entire* ACPIBacklight thread? I remember reading something about the range needing to be 0-0x400 and there is a modified version done by another developer later in the thread. If you read the entire thread there are several versions...

acpibacklight apply to dsdt, but the maximum brightness is the same. Ioreg dsdt here and I'll place the two ones to solve the problem would be appreciated.

What, exactly, is the behavior now?

You might consider taking a closer look at your DSDT methods for brightness. For example, I can see a test of OSYS >= 0x7D9 right at the start of the _BCM method:

Code:
                Method (_BCM, 1, NotSerialized)
                {
                    P8XH (Zero, Arg0)
                    If (LGreaterEqual (OSYS, 0x07D9))
                    {
                        If (LAnd (LGreaterEqual (Arg0, Zero), LLessEqual (Arg0, 0x64)))

And if you look at where OSYS is set (in _SB.PCI0._INI), you will see it sets to 0x7d9 if the OS detected is Windows 2009 (Windows 7).

Or, you could change it to:
Code:
                Method (_BCM, 1, NotSerialized)
                {
                    P8XH (Zero, Arg0)
                    If (1)
                    {
                        If (LAnd (LGreaterEqual (Arg0, Zero), LLessEqual (Arg0, 0x64)))

You should also verify that the kext is calling the methods as you expect. (Debug version and look at system.log within Console.app).

As I mentioned before there are several different versions of this kext. Have you tried some of the others?

I present you as one solution, but the problem was the same.
In addition, version 1.0 to 1.2 ACPIBacklight.kext and people using the modified ACPIBacklight.kext tried, but the problem is the same.
Brightness comes in Linux and Windows normally.
But that's not the hackin.

Why would Console.app fail to load?

Did you look at the DSDT code I mentioned?
