I agree. But it seems a bit nasty. Either flash chip knowledge in lar,
or lar knowledge in flashrom. Both is not very nice.

In case lar is in the path, flashrom could be told to run lar with the
options for the user, just asking the user whether he really wants to
continue (with a no warranty clause printed in capital letters ;)
