And because of course, something had to keep being mysterious:

When attempting to duplicate the boot rotation via pickel+sysfs, while I end up with what appears to be an identical modeset (i.e., 1440x1080, 16bpp @ rotation: 0 (Upright, 0°)), it turns out, not so much.

After implementing proper rotation for that "duplicated" modeset in FBInk, and updating KFMon to use that, my welcome message is still not positioned properly...
It's no longer upside down and RTL, but it's not positioned properly on the y axis (it's inverted: near the top instead of near the bottom).

-_-".

(And, AFAICT, no, it's not because pickel manages to change modeset between my init and my first message, because that behaves in yet another way...).

EDIT: Hmm. After running another set of experiments with *no* rotation tweaks at all, it *might* still be a race with pickel after all, that at least makes some kind of sense given the timing...
