Doh...  I didn't trust that error message because I knew my kernel
config had support for all the ciphers needed, I had added it as a
module when I first started using cryptsetup ages ago, to avoid
rebooting, but normally I run with everything built-in, and I forgot I
still had that as a module, so I didn't run make modules_install for
the new kernel... :(
