As an aside, I think long-term coreboot should have a config file in
flash and use that instead of nvram.
The issues with using nvram:
* it's small and it leads to weird hacks to store data
* the coreboot layout conflicts with the vendor layout and it's a
pain when switching between coreboot and factory bios
* the batteries frequently get old and nvram storage becomes flaky
Just my 2 cents.
