Lvm2 on LUKS @ boot time: volume group found but not importing

Question

I have so far succeeded in making ArchLinux boot as far as properly asking for my encrypted partition's passphrase and unlocking the encrypted partition (/dev/sda2) whererein lies the root filesystem; the encrypted partition contains a lvm2 group that has logical volumes on it for swap and root.  However, instead of importing the group, it simply acknowledges that one exists;
:: Running Hook [lvm2]
Scanning logical volumes...
Reading all physical volumes. This may take a while...
Found exported volume group "crypt" using metadata type lvm2
Activating logical volumes...
Volume group "crypt" is exported
Waiting 10 seconds for device /dev/mapper/crypt-root ...
Root device '/dev/mapper/crypt-root' doesn't exist. Attempting to create it
Should I just increase timeout (and how do I?), or is there something else I must enable? The last 4 of my hooks are (and I know them by heart at this point): usbinput encrypt lvm2 filesystems. I do not have
I am at my wits' end. I've tried everything from different mount points in fstab (i.e. /dev/crypt/root instead of /dev/mapper/crypt-root) to putting the encrypted partition in /etc/crypttab to changing the order of "root=" and "cryptdevice=" in the kernel parameters in menu.lst, and this is as far as I have gotten.

In https://bbs.archlinux.org/viewtopic.php?id=164267
there is a similar issue of today, but with a UUID naming instead of a label. Maybe you want to try the workaround described there with an udev-rule. If you re-typed the kernel line, please double-check it (asking that because you have lvm and LVM in there).
What's the problem with the "block" hook for you regarding the partition size?
The initramfs does not fit with the block hook? I'm asking that too, because the "block" hook includes the old "usb" one.
Is the usb-stick there at "/dev/disk/by-label/MARTINC" after boot?
