Comment 9 for bug 560717

OK, I've had a chance to test my workaround script, and it does work. I've attached it to this comment; drop it in /etc/intramfs-tools/scripts/local-top, and rebuild your initrds ("update-initrd -k all -u"). During boot, if the /dev/mapper directory isn't available, this script will load the dm_mod kernel module, wait a second, and then activate all LVM volumes.
