(I suppose this comes too late in the release cycle to make the change, but perhaps it's simple enough:)

With only minimal manual intervention, I found I could use today's Ubuntu Server 12.10 daily iso to install a system with luks+lvm and no separate /boot partition (which doesn't really have any security advantages, but it makes managing space on a smallish disk easier). If partman-crypto could manage the final 2 steps below, it would all be fully automatic. Thanks!

Steps:
1: go through the default installer motions
2: in partman, choose the manual option
3: create a single, whole-disk primary partition, use it as a luks encrypted volume
4: on top of that, create an lvm physical volume
5: insert lvm logical volumes for swap and / (I used btrfs, probably irrelevant)
6: finish remaining installer steps; find that grub install fails
7: drop into shell, per alt+f2, and chroot to /target
8: append "GRUB_CRYPTODISK_ENABLE=y" to /etc/default/grub
9: run "grub-install /dev/sda" (replace sda etc etc), then "update-grub", reboot
