There's a couple of things this should really have, if we're going to
include it in NetBSD:

1) Support in the very similar code for swapping to files.
2) random-key support, for data you don't care about keeping across a
   reboot (e.g. swapfiles, /tmp).
3) support for a key passed in from the bootblocks, and a mountroot hook
   to configure the encrypted vnd would be a huge win.
