More information... With the acpi "video" module unloaded, the brightness up/down hardware keys do nothing. And no ACPI events are generated. So this narrows it down to ACPI events.
With it loaded, when the buttons are pressed, acpid notifies both the X server and hald-addon-acpi that the buttons were pressed. Killing hald- addon-acpi does not modify the behavior. Thus, it's gotta be the X server itself getting it backwards. So I think some solutions might be: 1) Tell acpid not to notify the X server for these events, and control it with video_brightnessup.sh and video_brightnessdown.sh via /proc instead. 2) Find out where in the X server the brightness is being set, and fix it for Lenovo(?) models. This Ideapad Y530 has a "Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)" video card, and X is using the "intel" module.
