Thanks for the quick reply.  I did some digging, and found a patch set from
January, resurrected and forward ported to the current tip of flashrom on
github.com/petermartini/flashrom, and confirmed it worked well enough that
it worked on my chipset.

This was Boris' work, and I guess it was incomplete / petered out before
being committed; does it ring any bells?

It seems the thread petered out around

I'm happy to help, if I can, get that patch set merged in if there's work
to be done on it so I can upstream my chipset's specs.
