Ok, it's roughly what I expected. And it's still what I consider the hardest
way to implement this feature. For instance, the first line, it's a probe
command by definition (cf. fourth paragraph of the manual), that does much
more than probing. So at least we'd have to change all the documentation
because of this (I expect that this is just the tip of the iceberg).

So why, for instance, would this be worse:
> # tuxedo_unlock_me
> # reboot
> ...
> # flashrom -p internal -w image.rom
> # poweroff
