LCD problem

Hi all, 
      Me and a team are work on a Arm port of our OS (DexOS), to this
device, it is being written in FamArm (full assembly).
We are porting the no OS demos first, that are written in C.
This is going OK, but for two small problems, first it seem to write the
bmp file as if it big indian (we have left it as the vivi set it), changing
the 'HWSWP' make no differanc.
Second and harder to fix, is a 3-4 pixel black line at the bottom of
screen, this is hardware set as its still there when scroling.
I think the problem maybe that something more need setting up, as the no os
c programs do not do this.
I have the 3.5 lcd and i am using VM and 16bpp setup.
Here is a screenshot that may help.

Hello,

Have you looked in the new 2440test examples from 2009-07-19? There are
some changes in the lcd routines.
