From nickel (1080x1440, 32bpp, rota 1 (CW), fb origin at the top-left corner):
0 -> 1440x1080, 2 (UD), fb origin at the top-right corner
1 -> 1080x1440, 3 (CCW), fb origin at the bottom-right corner
2 -> 1440x1080, 0 (UR), fb origin at the bottom-left corner
3 -> Back to Nickel state.

From pickel (1440x1080, 16bpp, rota 2 (UD), fb origin at the top-right corner)
0 -> Back to pickel state
1 -> 1080x1440, 3 (CCW), fb origin at the bottom-right corner
2 -> 1440x1080, 0 (UR), fb origin at the bottom-left corner [That's the status at boot]
3 -> 1080x1440, 1 (CW), fb origin at the top-left corner

So at least that's consistent, and the final rotation equals input ^ 2
