Ugh ? If I understand things properly, you are copying all of highmem down to lowmem ? Hrm... I'm afraid in lots of case you'll run out of lowmem in the process. Actually, we should be able to use highmem even for snapshotting since the disk IO can then be directly be done from highmem pages...
(Though kmapp'ing/unmapping each page will be slow as hell)
