So far we used the wrong opcodes to access the DSI registers, so the register writes during DSI programming didn't actually succeed and left the registers unchanged. This wasn't a problem for the initial modeset, where the BIOS-programmed values happened to work, but after resuming from s0ix these registers are reset and failing to program them results in a blank screen.
