AFAICT, those modes break whitespace-mode because they define their
own display table without copying the display table that was in effect
before the mode was switched on. whitespace-mode does take care of
copying the previous display table, and doesn't override the way the
formfeed is displayed AFAICS. So maybe activating those other modes
_before_ whitespace-mode will do the trick? (Caveat: I didn't try
that.)

Not sure how this question is related, please elaborate.
