@jackie_w: Thanks

.
Code:
-- detected a change in framebuffer bitdepth, refreshing -- 16 -> 32
-- new fb state -- rota 3 @ 32bpp
That's what was missing ^^.
(That's something I knew needed to be done going in [it's essentially why
fbink_reinit exists], but that I apparently completely forgot about along the way ^^. Compounded by how I did the initial testing (by running MiniClock manually long after boot, so everything's already setup properly by Nickel), and how my devices are setup (with KFMon's boot progress bar, so no pickel), and the fact that with a bit of luck, the broken setup could actually mostly work, this completely flew under the radar -_-". Extra fun fact: I did it properly in the FBInk
daemon 
.).
