dmesg for unify-flip-modeset

Sorry, I booted with the wrong kernel parameters. This is the correct dmesg
log. The screen stays on and black even in Xorg. So I assume no mode switch is
happening between console fb and Xorg. This time I got 'clever' and unplugged
the TFT and reconnected it, so it got reinitialized and showed me an image. So
the problem could be solved by a special hardware flip switch in the HDMI cable
that interrupts the connection between gfx card and monitor for a moment.
Whenever you boot your computer you flip the switch and the image shows! But a
software solution is still preferred.
