Which tree did you base this on?  16045 is a local version number (only 
has meaning in your repository).  7b8ab50c2b04 doesn't appear to be in 
-unstable.

In general, if you're building a domU kernel, it should be safe to use 
older changesets.  If you're building a dom0 kernel, you really want to 
use a set of tools that is matched with the dom0 kernel.  I don't think 
there have been any huge changes in the tools so I think it would be 
fine to pull the tools from the same snapshot that you took 2.6.15 from 
(which I assume is around 8740:3d7ea7972b39).

I tried running -unstable on Dapper a couple of weeks ago and Xend 
wouldn't start.  I only run Dapper on my laptop so I haven't 
investigated much further.  Have you had any problems with Xend?
