Thanks - that's exactly what I was looking for. I might even have found
it if they'd actually shipped it in Sarge - grrrr. And to add insult to
injury there's no lvm package on backports, so I had to scratch around
for a while to find apt-source that would build happily on amd64. Oh
well, it's fixed now....

If anyone else comes across this little irritation, there's a nice set
of packages at http://blog.blackdown.de/, which rebuild quite easily.
