it's not too bad if you have access to SMT rework equipment [1].  good
flash images exist, right?   worst case scenario the flashes get
desoldered, externally reprogrammed, and soldered back in.  ideally
sockets could be added or the write-line trace cut to help keep the
problem from happening again.

what's the packaging and vendor part number on the flashes in question?

I might need to buy a new personality module for the burner here at
work, but if it will help keep some VAXen alive, it's worth it!  :)

[1] part of the equipment available to me includes a nimble-fingered
    co-worker.  :)
