Currently the only replacement is in cconv.el near the beginning of the file:
;; TODO: (not just for cconv but also for the lexbind changes in general)

Yup, the *Backtrace* buffer's content and major-mode are not properly
saved&restored upon entry to and exit from the debugger. Patch welcome,
Stefan
