@kovidgoyal: Thanks for the KP 2.5 hint, that's indeed way more practical to check this kind of stuff
.
Anyway, got it to pop up in KF8 (standalone) with this version of the patch.
Not sure what did it, since I simply updated the reported KindleGen version, and tweaked the EXTH flags to match KindleGen (and keeping the fontsignature). I'm guessing the EXTH flags did the trick... Since I didn't look at the joint output at all, there may be similar tweaks needed there to get it working on joint files. (I used the flags from the mobi7 part, there's another bit set on the mobi6 part, I put a comment about it in there).
On a sidenote, KG 2.5 adds new stuff in the exth headers:
Code:
524 (524): 'fr'
525 (525): 'horizontal-lr'
535 (535): '0626-3a91e28'
524 seems to be the language of the book (again).
525 looks related to the fixed-layout/orientation stuff... The firmware on the touch is a bit more verbose about it, I've seen a bunch of stuff related to this in my logs:
Code:

535 is the build/rev number of KG
EDIT: Killed deprecated attachments. Fix merged upstream.
