Based on this..., although I can't reproduce the problem on my systems, I wanted to see if there was a way to make a generic ALS, and if FakeSMC.kext with those extra keys was a problem on other computers...
So I added the keys... this is the diff (it was a little unclear which keys you were adding, but this is what I gathered by reading between the lines):

The FakeSMC.kext with this change is attached.
I didn't have any issue with the updated FakeSMC.kext (without SSDT-ALS0.aml) on a desktop, nor one one of my laptops.
So..., then I move on to enabling a Fake ALS that is generic...
I did a little reading on ALS in the ACPI spec... and decided to create a minimal SSDT-ALS0.dsl to serve as a generic, never changing, fake ALS:
Code:
// Fake ambient light sensor device
DefinitionBlock("", "SSDT", 2, "hack", "ALS0", 0)
{
Device(_SB.ALS0)
{
Name(_HID, "ACPI0008")
Name(_CID, "smc-als")
Name(_ALI, 300)
Name(_ALR, Package()
{
//Package() { 70, 0 },
//Package() { 73, 10 },
//Package() { 85, 80 },
Package() { 100, 300 },
//Package() { 150, 1000 },
})
}
}
//EOF
As you can see, the version above always returns 300 for the _ALI and only has one mapping in _ALR: a neutral mapping (100) for 300 lux)
I actually tested both ways with the other items in the list, and without...
Both same result...
This does get me the "Automatically adjust brightness" checkbox in SysPrefs->Displays, so maybe it is also adequate to fix the brightness restore (and relies on no specifics of any particular native ACPI).
The pre-built SSDT-ALS0.aml is also attached.
Please test.
