I have stared at the hex dumps but I really do not see any good candidates for where this information is encoded.
The "MobiPocket Creator" tool creates v4 files which work just fine on the Gen3. I've just used it to create a new version of Dickens' "Bleak House" (available from the Mobi book forum). Might it be worth comparing the output from a simple book from "MobiPocket Creator" and your tool, and see if there are any differences?
