I recently went through this (with the added complication of some bad 
metadata) and you have a few options.

The best one may be to use dd (with NOERROR) to raw copy the contents 
from the old disk to a new one of the same size and then use the new one 
when doing the pvmove.

Another path is to upgrade to LVM2 (you may have to do this anyway, I 
needed some functionality in the LVM2 pvcreate to pull my stunt off) and 
use the "partial" feature. I haven't tried this myself.

There are more details of my tribulations just a few weeks back in the 
list archives, but feel free to ask if there's something missing (I had 
some private conversations with Heinz on the topic as well).
