Sorry, bmarkus. You've misread my post. I said  Xorg-big  as in "not small", not  Xorg-bin  as in "binary".
With "-big" I wanted to imply that it's bigger than  Xorg.tcz , because it contains  Xorg.tcz  plus all its deps.
On top of that, I have the feeling that the language barrier gives us a hard time. English isn't my mother tong, so my wording might be confusing at times.
