Yeah it seems like we're having to speculate where the problem actually lies
because I for one still cannot find any documentation or insight on how it's
*supposed* to work.

It looks to me like they moved most of the ACPI event-handling functionality
out of the /etc/acpi scripts and into gnome-power-manager,
guidance-power-manager, or kpowersave which listen for the events via HAL. If
that is the case, then neither guidance nor kpowersave seem have any
provision at all for handling brightness key events in the first place, so
perhaps the modifications to /etc/acpi should be reverted for the brightness
keys.

On the other hand, this could be dead wrong, in which case, somebody who knows
how these subsystems are set up in (k)ubuntu, and/or where to find said
information, *please* chime in.

And I tend to agree that having to be logged into your DE to change the screen
brightness using dedicated hardware keys is... not ideal.
