From my understanding, to get around that you can just save the affected environment explicitly (like in normal games.) Having a large amount of affected areas will eat up space, though.
yes basically - the world 'starts' as fully procedural, but as you go around affecting it (through destruction etc), the game just needs to save the changed pieces from that point onwards. Either way, the amount of saved info is still going to be dramatically lower than purely hand-made content.
This article (analyzing procedural content used in Oblivion) has a good breakdown. The same principles can be applied to Fallout3 as well:
