You can play around with setting the back ground to solid
colors Red
Green Blue etc.

And dig into the driver. Obviously something is wrong.

I can't help you from the information you have given me.
By driver I mean the kernel  /dev/fb driver.

It looks like your driver may not be reporting its real
layout.

Is it a custom driver ?
Is your lcd panel really 18bpp ? ( your symptoms suggest
this )
RGB16 mode should work on all color lcd devices.

For all I know its custom hardware and somebody munged the
board.
This is not exactly uncommon :(

See
http://linux-fbde
v.sourceforge.net/

Its only a few lines of code to upen the driver yourself and
play with
the setup.  I think it would help you a lot if you spent
some time learning
about the fb driver if you plan to use it in and embedded
environment.
