Not really.

1. Old installation using one of more reiserfs file systems.
2. Install Lenny without wiping; use one or more reiserfs file systems.
3. Worst-case scenario file system failure.
4. (reiserfsck --rebuild-tree) -> Links files from the old file system into 
the new file system.

If you are going to put reiserfs on a block device, it is not overly cautious 
to erase the block device, to avoid (reiserfsck --rebuild-tree) from 
performing necromancy.
