I ended up using xbacklight bound (in my window manager) to the brightness hotkeys for both my Lifebook E744 and my Vostro V131, which has a royally borked ACPI backlight control implementation. It seems using userspace helpers for backlight control is the new normal [1]. Yes, you lose console brightness control; I can live with that, YMMV.
