I believe that HP 6470b and 8470p can share the same mainboard.
I don't know... compare DSDT headers.

RehabMan, I just noticed you've pushed some new commits to your OS-X-ACPI-Backlight repo but unfortunately the link for downloads does not work anymore (404 error). Have you seen it?
One little issue in the makefile:
target distribute:
cp ./PatchCoconut.sh ./Distribute
It's not supposed to be here, right?
I have just compiled it, installed the kext, repatched my DSDT (also got rid of blinkscreen) and - what a fantastic job, RehabMan. Everything is working smoothly, I love how the transitions look just like on a real macbook. The backlight setting is remembered after sleep/reboot as well. And what's most important for me - I can finally work during the night without having constant eye strain. Absolutely great job, thank you!
# example setting it to 100
ioio -s ACPIBacklightPanel RawBrightness 100

// extended _BCM/_BQC for setting "in between" levels\n
Method (XBCM, 1, NotSerialized)\n
{\n
// initialize for consistent backlight level before/after sleep\n
Store (0x80000000, LEVW)\n
Store (KLVX, LEVX)\n
// store new backlight level\n
[B] // comment this out.... If (LGreater(Arg0, XRGH)) { Store(XRGH, Arg0) }\n
// and less so, this one.... If (LLess(Arg0, XRGL)) { Store(XRGL, Arg0) }\n[/B]
Store(0x80000000, LEV2)\n
Store(Arg0, LEVL)\n

The data used on the 4530s can be improved. I think the curve is a little shallow at the beginning and too steep at the end. In addition, the lower values can be pushed lower (the top level could go higher too). I'm planning to calibrate against my MBA.

Yeah, I agree. While I'm glad there's still room for improvement, I'm guessing it's going to be pretty difficult to set up the "steps" so that they're consistent in terms of a smooth, gradual brightness change.
Thanks for the instructions, I'm going to play with ioio straight away.
