If needed, I think we could make it work reasonably cheaply with
something along the lines of (100% guaranteed untested code):
(let (pos lines (eol-offset 0))
(while
(progn
(setq pos (byte-to-position (+ pm byte (- eol-offset))))
(setq lines (1- (line-number-at-pos pos)))
(not (= lines eol-offset)))
(setq eol-offset (+ eol-offset lines)))
pos))
