I had i915 weirdness with different chipsets at different times. Other than the oops happening in drm_vblank_put it occurred to me that a random X screensaver must have been active when it happened.
I didn't manage to trigger the panic over night with the problematic kernel in runlevel 3 (console), nor did it occur with a vanilla 2.6.39.1 during the day. I shall have to continue testing.
