from the answer of Jan P., I would say replacing postfwd v1 shouldn't happen (yet). Beside that postfwd2 hasn't a upstream tarball, at least I haven't found one. Do you feel, we need postfwd2 in squeeze? I personly wouldn't hammer postfwd2 into squeeze, cause the testing period would be really short.
