I used your find command and copied the grub.cfg file into place. It "just worked". Cool indeed! Practically speaking, I could copy the file into place every time that I reconfigure the system. But for bragging rights, I've got to get it automated. I'm reading through the code, looking for the best approach. I'm a clojure programmer by trade; scheme is new to me.
I think I will try to make a package for flashrom and the libreboot utilities, but I like this solution of just copying a file into place.
