I didn't do any debugging, but I set a Custom PS2 Map entry, which is e02b=0. It seems to have fixed the problem. Thanks for the guide.
By default e02b is already mapped to nothing (0x80) (PS2->ADB), which would generate a "bonk" audio sound when pressed.
If your brightness keys generate both a PS2 e02b and ACPI EC queries, it is a good idea to make the PS2 code do nothing, because you don't want to hear the 'bonk'. Note that PS2 code 0 is also mapped to ADB 0x80, but there might be a special case in the code... further debugging might explain the difference.
