Yes, I tested on qemu. A simple udev rule like this one in the initramfs
will also do the trick:

ACTION=="add|change", SUBSYSTEM=="block", KERNEL=="sr*", GOTO="cdboot_start"

IMPORT{program}="/sbin/blkid -o udev -p $tempnode"
ENV{ID_FS_USAGE}=="filesystem|other|crypto", ENV{ID_FS_UUID_ENC}=="?*",
ENV{ID_FS_USAGE}=="filesystem|other", ENV{ID_FS_LABEL_ENC}=="?*",

About memdisk: It works fine on 64 Bit, but not on 32:

Appending vmalloc=256M to the kernel command line fixes that, but it is
apparently not without side effects - should be good enough for the ISO

I am uploading ISOs that work to
http://alberich.archlinux.org/misc/testiso/, they should be there in
about an hour.
