This should be a fairly minor technical problem; the theoretical
problem can be solved by analogy with a standard procedure for
specifying a location in a multi-dimensional space, by using
Cartesian coordinates.  Instead of saving one address as the
bookmark, save them all, and possibly the frame structure as well
(in case there's some trouble getting the base document back, you
can still do a partial recovery).  A return to the state at the
time (s)he bookmarked it is what the user wants; it could get
tricky in principle, as you might need to include any number of
addresses in your bookmarks, but in practice the number shouldn't
get very big most of the time.  Browser vendors would just need
to allow more space for saving each bookmark, and browsers would
retrieve complicated positions more slowly than simple ones (but
then, they would get to them more slowly in the first place, so
that shouldn't surprise users).

Why can't you?  It must be a countable number, so there's no problem 
with this in principle.

Just store that information in the bookmark as well.  You can store in
the form of HTML, as it was originally written.

If you store a bookmark as HTML, the mapping of URLs to frames is no
harder than composing the HTML for the original framed document.
