If this is halakhah le-ma'aseh (practical), my initial reaction is that it's inefficient; let it defrost overnight. If it's a halakhah le-shemah le-kayf (theoretical, for fun) question, I hope someone who has read up on the issue weighs in!
I'm not a posek, so I won't comment on whether it's permissible. But it doesn't sound to me like nolad. The usual cases of nolad are things that never had any existence (at least, in useable form) before Shabbat/Yom Tov. The frozen food did exist, and was perfectly edible before it went into the freezer, and can even be eaten (albeit with difficulty) right when taken out of the freezer. So it doesn't seem to me like nolad.
It depends on the food, as far as I understand it. You don't want to reheat anything that has significant oil or fat in it, unless those oils and fats are going to be absorbed by whatever else is with it.
My cousin's rule of thumb was, if you can SEE the reheated fat/oil, than it is nolad and cannot be reheated for the Sabbath.
