No idea, I was just diffing the register writes looking for sources of
discrepancy. The Chromium OS 3.14 kernel tree that Buddy uses doesn't

The firmware I'm loading is: `FW info: type 01, - version: 00.00,
build 77, source commit id: 876ac6906f31a43b6772b23c7c983ce9dcb18a1`.
Hashes the same as the upstream binary.
