Freezing the fs looks to make the log zero. So assigning any device/file for the external log would work.
My mistake was not making the log dev an LVM. However I don't if a log on an LVM would have worked anyways.
At any rate, HTH some one else.
Thanks for the follow-up, and worth a wiki entry, imho
