As of Linux 3.5, it is not possible to update the SecureBoot database from userspace because the sysfs implementation only supports variable data up to 1KB in size and this is exceeded by even a minimum key database of one key.

Matt Fleming has accepted a patch from Matthew Garrett to add a new filesystem that supports larger variables. Please consider backporting this (as an SRU) to both quantal and precise.
