load module error

[Alexander Golovin <alex.golovin@mail.ru>]

 I've tryed to load modules for my partition encryption, and had an error: 

#modprobe sha256
WARNING: Error inserting padlock_sha (/lib/modules/2.6.26-1-686/kernel/drivers/crypto/padlock-sha.ko): No such device

 Is it very important error for this module work? Can I work with this module with that?

My kernel is: 2.6.26-1-686 #1 SMP Wed Aug 20 12:56:41 UTC 2008 i686 GNU/Linux
