I've resorted to adding PNLF to DSDT to get backlight working on EEE PC 1005PE
after upgrade to 10.6.6.
Now that OSX is controlling backlight, I would like to use keys to control it.
OSX uses keys that map to F14/F15 and that seems to map to location of
Pause-Break/Scroll Lock from PS2 keyboard.
There is logic in ApplePS2Keyboard.kext that maps Scroll Lock to correct
Function Key and if you press this on laptop the display is dimmed and a
graphic pops up showing what OS is doing.
Pressing pause key does not work for increasing backlight brightness. I traced
this to a bug in ApplePS2Keyboard.kext. Even though it goes out of its way to
explain how extended sequence of Pause works, it ignores it in the end.
Attached is patch to gets it working and allows adjusting brightness using
Pause key.
Ideally, the laptop hotkeys for same feature would be converted to same F-keys
but that seems a job for another kext.
