Alright guys, I'm no expert at all and basically tried to hack myself through the scripts, and now I'm not completely sure what I actually changed... but anyway, I *think* in /etc/acpi/events/sony-brightness-down it originally read:

event=sony/hotkey SPIC 00000001 00000010

However, when I use acpi_listen and the corresponding button, I get

sony/hotkey SNC 00000001 00000010

Note it reads SNC, not SPIC (whatever that means). I now changed SPIC to SNC in /etc/acpi/events/sony-brightness-down, and suddenly I can adjust my brightness with the corresponding keys (while still referring to the original /sonybright.sh as event)!

So is that the whole problem after all? I'm confused...
