linux-modules for -kvm does not include dm-crypt

I was playing with an lxc virtual machine today and attempted some use of luks. a cryptseutp open fails with strange error message:

$ printf %s foobar | cryptsetup open --type=luks --key-file=- /dev/atom0/smtest_enc smtest
device-mapper: reload ioctl on failed: Invalid argument
$ echo $?
1

The reason is that the '-kvm' variant does not include dm-crypt.ko kernel module.

That by itself doens't seem like all that crazy of a thing, but if you notice the following 4 all do have dm-crypt, -kvm seems like it should not be an outlier.
