no, i was talking about a 'format' i.e. a \dump'd thing, i have no clue 
what \savebox does, and it may do image trickery as much as it likes but 
in the end the image will not be in the format file

afaik the problem only occurs when a \dump is done and an option is then 
  to \let\dump\end or so

anyhow, it's a dump related problem, not a macro package related one
