Is the bug report perhaps available somewhere? I'd very much like to fix this as it 
is causing many support issues since for example https://fedoraproject.org/wiki/Tboot
suggests

"You may download all of the ACM modules into /boot and list them all as 
modules in your grub.conf. tboot will pick the right module for your 
platform. "

I can't change that wiki page as edits are currently not allowed even if I 
create an account.
