It's true that the sensors are usually not the same, but quite often in these comparisons the newer better tech sensor is actually in the APS-C body (Sony being the apparent exception since they're iterating their FF so fast).  I think it is important to mention the light though,  because it is why FF appears to be less noisy, not because of bigger pixels and whatnot (actually that matters, but not in the way the average Joe thinks it does).  Maybe we should try to make it more clear that it's not a slower lens per se, but a slower-ish (I don't like the terms fast and slow for lenses... I know why they are used but feel they're a bit misleading) lens/sensor combo and it's not different than their expectations probably were anyway for the combo?  Light per pixel isn't the issue, it's the total amount of light given the same final size comparison, pixels aren't needed to derive this at all.
