This means the dm-crypt module wasn't loaded, most probably because it 
is not exactly the same version (same GCC, same options, etc) as the 
kernel itself. This doesn't sound like a cryptsetup problem...

What kernel are you using? Are you sure the dm-crypt module is ok? Are 
you able to manually insmod dm-crypt?
