I have found a workaround.

Before I run S00psplash,

I will do 'fbset -depth 16'

Then psplash looks OK, and omaplfb loads, and the applications look right.

Now I only need to figure out how to do 16 bpp in the Device Tree file 
for the da8xx-fb driver.

For the tilcdc there is the tilcdc-panel.c file.
Is there something similar for the da8xx-fb driver?
