On an (rather old) ThinkPad X41, which also uses i915, brightness adjustments stopped working altogether in v3.14-rc1 (I haven't used its docking station in the v3.14 release cycle). In v3.13.y things behave as expected. So perhaps there's actually a more general problem here.
I presume different problems. Does the ThinkPad X41 have gen3 graphics? (See e.g. /sys/kernel/debug/dri/0/i915_capabilities) If yes, it might be https://bugs.freedesktop.org/show_bug.cgi?id=75001
