Perhaps there is a problem in which the reiserfs module does not get loaded
before you need to read the root partition?

If you isolate the problem to where you think it is a reiserfs bug, please let

This is entirely correct.  Moving tails around costs performance, ReiserFS
cannot give you something for nothing in this respect.
