Live CD - luks - lvm2 -- Can't mount encrypted lvm2 logical volume via Live CD

While running rawhide, I can no longer boot using rawhide packages from
11/06/2010. I keep getting asked for the LUKS passphrase. After I enter
two characters, it says the passphrase is invalid. My passphrase is about
30 characters in length.
In my efforts to "keep all the pieces", I'm trying to access the lvm logical
volume that is encrypted to save at least some of the pieces. :-)
I perform the following steps:
1) Boot the live CD (F14) (X64)
2) Open a terminal window
3) su -l root
4) modprobe dm-crypt
5) sudo cryptsetup luksOpen /dev/sda6 crypt1 (sda6 is the encrypted LVM)
6) modprobe dm-mod
7) [root at localhost async_tx]# vgscan
Reading all physical volumes. This may take a while...
Found volume group "vg_dubby" using metadata type lvm2
8) [root at localhost async_tx]# vgchange -a y vg_dubby
3 logical volume(s) in volume group "vg_dubby" now active
9) [root at localhost async_tx]# lvscan
ACTIVE '/dev/vg_dubby/lv_root' [50.00 GiB] inherit
ACTIVE '/dev/vg_dubby/lv_swap' [9.81 GiB] inherit
ACTIVE '/dev/vg_dubby/lv_home' [664.25 GiB] inherit
10) [root at localhost async_tx]# ls -ld /media/*
drwxr-xr-x. 2 root root 4096 Nov 8 22:14 /media/home
drwxr-xr-x. 2 root root 4096 Nov 8 22:14 /media/root
11) [root at localhost async_tx]# mount /dev/vg_dubby/lv_root /media/root
mount: unknown filesystem type 'crypto_LUKS'
I'm at wits end. Any suggestions?
PS: I posted yesterday on "Users", but got no response. Since this problem
was originally caused by a rawhide failure, I took the liberty of posting
here as well. If that's inappropriate, please be gentle. :-)
