~$ cat /boot/dmsetup-targets 
crypt            v1.7.0
striped          v1.2.0
linear           v1.1.0

lsmod isn't available in the initrd.  I could try adding it and
rebuilding if necessary, but my attempts to repackage initrd's are
often incorrect.

~$ cat /boot/proc-crypto 
name         : aes
driver       : aes-generic
module       : aes_generic
priority     : 100
refcnt       : 1
selftest     : passed
type         : cipher
blocksize    : 16
min keysize  : 16
max keysize  : 32

So it seems that cbc and sha256 are indeed not being properly loaded.
But this was after I had manually modprobed cbc.ko and
sha256_generic.ko (without error).  Any way to figure out why they
aren't being properly loaded?
