Hmm. Interesting!

I agree. That's why lar should know about flash chip sector sizes.
And/or flashrom about larballs.
The idea is to rearrange the files in the larball apropriately for
the current flash chip before writing.

But it creates another quite real problem for the first upgrade to LB
where we need to distribute the bootblock separately. I think that's
a _really_ undesirable scenario. :\ Especially since it will be the
common case for some time still.
One file is no file, two files are two files too many. ;)
