Hi Andreas,
I tried to test the serdev-w2sg0004 driver but it was not configured.
As soon as I did set CONFIG_SERIAL_DEV_CTRL_TTYPORT=y the w2sg driver seems to work
(with some other Kernel Warning about some duplicate /sysfs file), but now I get the
exactly same display error symptoms as you have
- a while flickering horizontal stripe near the top of the screen
- and: [drm:omap_crtc_error_irq] *ERROR* lcd: errors:

[ 18.336181] [drm:omap_crtc_error_irq] *ERROR* lcd: errors: 00004000
All this long before X11 starts. So now I have the same error on my screen :)
And it looks as if serdev support changes something in the init sequence.
BR,
Nikolaus
