I suppose it's also possible that a full stomach makes you drink more slowly. It's hardly a scientific study, but just an observation that I feel the effects of the same volume more acutely.
While alcohol can be absorbed by the stomach, where you have an empty stomach, over 80% of the absorption occurs in the small intestine. When food is in the stomach, the pyloric valve that regulates flow from the stomach to the intestine closes to hold the food inside for digestion, which also hold the alcohol in where it is less readily absorbed.
Because of this delay in the majority of the alcohol getting to the small intestine, it delays the effects of the alcohol, which does have a minor impact (10% reduction) in your peak concentration, but the overall effect is very small, and drinking 5 beers with our without dinner will result in the same level of intoxication, as far as legal limits are concerned. Having an extra drink because you ate so it won't affect you is a myth, and will likely result in your being more drunk due to the higher drink count.
I think the issue comes in with how much are you drinking in total.
If you have 2 beers in 30 min on an empty stomach, you'll probably be impaired because it's being processed into the blood stream pretty quickly. However, if you have 2 beers with a meal, the absorbtion rate is slower, which gives your kidneys more time to process it on top of the slower absorbtion rate.
However, if you have 5-6 beers in an hour or two, the fact that you ate isn't really going to be a huge factor in how drunk you get.
