Good catch Rudolf - that could be the problem.

Does coreboot disable all BARs at start?  Would SeaBIOS have to
remember which BARs it disabled and then reenable them after the
optionrom is copied?

Also, does anyone know a reliable way to reset the machine?  It might
be simpler to have SeaBIOS just do a full reset when it detects a
partial reset.
