For what it's worth: /usr/bin/X is a wrapper that runs setuid root.
After doing minimal initialization that requires running setuid root it
drops root privileges and exec's the actual Xserver - /usr/bin/Xorg.
There may be other reasons, but one thing that comes to mind is that
this approach keeps the code that needs to run privileged to a minimum
to reduce the risk of security holes.
On debian "etch":
$ dpkg -S /usr/bin/X
x11-common: /usr/bin/X
Seems it was packaged differently on the version of debian that you are
running.
