Seems the message below and the thread have reveived no attention/answer. The output presented is quite tricky. Looks like if lmer (lme4 0.9975-10) has accepted a negative binomial link with reasonable estimates, although it was not designed for... What can one think about result validity ?
Well, I can believe that lme4 0.9975-10 may have allowed families that were not hard-coded (e.g., negative binomial with a fixed overdispersion parameter). I would expect the results to be reasonable. However, lme4 has gone through a lot of changes. If you have an old copy around and your results pass all the sanity checks you can think of, I might go ahead and use them -- otherwise you will have to deal with glmmADMB, WinBUGS, AD Model Builder (or lme4 with quasipoisson family) ...
