Hi,

Here is a proposed patch to correct the following XFdrake
problems:

o Inverted logic about the Composite extension. It is enabled
by default in X Server 1.4 or newer.
o Incorrect, and unnecessary symlink being generated from
/usr/bin/Xorg to /etc/X11/X.
o Doesn't work if /etc/X11/xorg.conf is a symlink to a file
elsewhere.


Pixel please review. It took me some time to understand the
logic of how data is managed internally, and I am still not
100% sure it is following the coding style or main logic, etc.
