So, 32bpp "works" but 16 is broken ... I guess my palette fix is just a lucky
hack and I need to dig deeper in fb code to have a better understanding of
the color map. 

I should have provided you two patches in the first place. Do you want the 
device tree data fixes for the frame buffer screen properties ? It helps to 
have a display for little endian guests even if the colors are wrong.

Thanks,
