I had exactly the same problem.  My guess is that it has something to do 
with the device-mapper not getting along with the x86_64 kernel. 

This is how I proceeded:
1) booted knoppix
2) loaded the dm-mod, and the dm-mirror modules:
    modprobe dm-mod
    modprobe dm-mirror
3) pvmove /dev/sddc1 ... and so on

seems to work fine,
