Looks like it works, albeit the first level is automatically dropped
out by lm(). I'll manege to do something with that.
The second option looks good too.

The arma function in the tseries package allows estimation of models
with specific ar and ma lags with its lag argument.
For example: y[t] = a[0] + a[1]y[t-3] +b[1]e[t-2] + e[t] can be estimated
with the following specification : arma(y, lag=list(ar=3,ma=2)).

arima() certainly does. You missed the 'fixed' argument that allows ARMA
coefficients to be set to any value, including 0.
Note that arma() does not do ML estimation. For that you have to worry
about invertibility, and it can be much harder to do the optimization with
constrained parameters.
