The encryption modules are all available except for cryptd (config option 
CONFIG_CRYPTO_CRYPTD). Also enabled are CONFIG_BLK_DEV_DM and CONFIG_DM_CRYPT 
(both as modules), so I suspect you just need to load the modules to get 
going.

Please note - I built the kernel package(s) using Debian's default 
configurations except for ISO9660_FS, EXT2_FS, EXT3_FS, and REISER_FS 
options - These are compiled in to the kernel (perhaps XFS_FS should be too).

Sounds like you need to load the dm_crypt and aes modules - If any others are 
missing, let me know and I'll rebuild the kernel.
