I've removed some unrelated configuration (for normal/fallback) and some debug stuff from that configuration.
Here's what the git revision corresponds to:
$ git log --oneline 5a16282fa6 [DO NOT MERGE] mainboard/lenovo/x60: Add TPM 1.2 mainboard support 4cf7873412 payloads/external: GRUB2: Fix build error. b45bbb253f nb/intel/i945: Fix SPD dumps
Here's the relevant parts of my grub.cfg:
