no! If you are on ARM you can use ARMORED from
Originally it was developed in order to withstand cold boot attacks on
ARM platforms (smartphones).
If you change some code to support a boot promt (see tresor patches), it
should be possible to login with a keyboard (touch screen -> good luck ;)).
Normally cryptsetup is used to setup the key derivation of a passphrase
in order to set the dm-crypt cipher key. That's why it is needed.
