[ltp] xorg dualhead-configuration on r50

[Jan Girlich]

Hi there,

I followed the Instructions found here:
http://www.chronox.de/x40_linux/linux_on_x40.html#dual_head_configuration=
_with_x_org

This is what my xorg.conf looks like:

But I don't get Dualhead as I want it. All I get is my LCD duplicated.
So I took a look in my logs and found this. Note the line about Pipe B.
