I'm a little hesitant about doing this, in large part because there have
been cases in the past of machines being bricked by writing to NVRAM.
Hopefully those problems are a thing of the past, but that history still
makes me wary of doing this globally.

Why is it so important to have this loaded by default, rather than
loading the module when trying to collect crash data?
