If it's built in, why efibootmgr doesn't work?

Title:
/sys/firmware/efi/vars unavailable (efivars module not loaded)
To manage
Examining both the Oneiric 11.10 and Precise 12.04 kernel configs,
CONFIG_EFI_VARS is built into the kernel for each of those releases:
config.common.ubuntu:1536:CONFIG_EFI_VARS=y
This was built in due to Bug 837332 as debian-installer relies on having
access to efivars when installing in EFI
apport information
** Tags added: apport-collected precise
** Description changed:
It looks like the module efivars is no longer built in the kernel on
Ubuntu 11.10 and 12.04 (both are amd64 versions).
root@laptop616:/efi/efi# ls -slah /sys/firmware/
razem 0
0 drwxr-xr-x 4 root
I tried running apport-collect, but it constantly hangs and never
finishes anything.
