Talk about wrong: after decompiling the DSDT, I found the important
parts of the _BCL, _BCM, and _BQC methods to be all wrapped inside a
"If (LEqual (OSYS, 0x07D6))".

Basically what that means is that LCD brightness query and control is
only available to ms vista.
After fixing that crap, surprise, I have a working
/proc/acpi/video/VGA/LCD/brightness

Not of much use for me anyway, since the Fn brightness keys work, and
I barely use powersave profiles, but it does get you wondering... what
do those engineers have for brains?

Or rather... does the fact that Phoenix and MS are holding hands turn
into explicit disabling of basic ACPI functionality for other OSs? If
that's the case, I bet the EU court would squeeze out another couple
hundred million dollars from the both of them (but unlike MS, Phoenix
won't be able to survive that -- which would be better for all of us
(rant over :) ))
