When I referred to "pagination information from within the mobi" I actually meant the page number anchors. If the KindleUnpack output is anything to go by, the anchors in the KF8 part survive the compilation while the page anchors in the Mobi7 part are lumped together with other anchors as <a id="fileposXXXX" /> anchors. (KindleUnpack apparently also cannot restore NCX pageLists.)

AFAIK, KindleUnpack doesn't distinguish between pageNNN anchors and other anchors in the mobi7 part, which is not really surprising since the tool predates the introduction of "real page numbers."

That seems to be the sticking point. If finding page number targets was that easy, the extremely talented guys who reverse-engineered the Mobi7/KF8 file format for Calibre probably would've already added code that detects pageNNN anchors in Mobi7 files and used them for generating .apnx files with real page numbers in them.

IMHO, it might be helpful to cross-post your question to the KindleUnpack thread, since the KindleUnpack developers are intimately familiar with the file format and might be able to give you some pointers. Maybe one of them might even like the challenge to be the first one to develop code that'll allow to generate an .apnx file with real page numbers, if at all possible.
