I can reproduce the problem, with error messages:

> sdem <- errorsarlm(eq, data = COL.OLD, listw = W, etype = "emixed",
+                    method = "eigen")
Error in estimable.default(lm.target, cm) :
   `cm' argument must be of type vector, list, or matrix.
In addition: Warning messages:
1: Function errorsarlm moved to the spatialreg package
2: In spatialreg::errorsarlm(formula = formula, data = data, listw = 
listw,  :
   model configuration issue: no total impacts
> traceback()
6: stop("`cm' argument must be of type vector, list, or matrix.")
5: estimable.default(lm.target, cm)
4: estimable(lm.target, cm)
3: as.matrix(estimable(lm.target, cm)[, 1:2, drop = FALSE])
2: spatialreg::errorsarlm(formula = formula, data = data, listw = listw,
        na.action = na.action, Durbin = Durbin, etype = etype, method = 
method,
        quiet = quiet, zero.policy = zero.policy, interval = interval,
        tol.solve = tol.solve, trs = trs, control = control)
1: errorsarlm(eq, data = COL.OLD, listw = W, etype = "emixed", method = 
"eigen")

I think that the construction of the specification matrix for 
gmodels::estimable() is faulty; will explore whether no-intercept is 
supportable.
