Oops. Is there some version/whatever check I can run from flashrom and
degrade to transactions <=62 bytes for older libftdi versions? Silent
data corruption at runtime is really nasty, especially if the user
wasn't warned.

That's possible. Your modem status byte issue description fits the bug
pretty well, so I think the additional debug code may not be required.
Jeremy, would you be willing to test some flashrom patches (pure read,
no write)?
