I would also suggest that you be very cautious in calling the
intervals generated from the conditional modes and their conditional
variances (i.e. the numbers you get from ranef(fit2, postVar=TRUE))
"confidence intervals".  They are certainly *some* kind of intervals,
but you can have a fine philosophical argument about what they mean ...
