I believe the problem is that PGF (the graphics layer below TiKZ)  
doesn't recognize xetex automatically. Your example works for me if I  
add the line

   \def\pgfsysdriver{pgfsys-dvipdfm.def}

before loading the TiKZ package; this explicitly sets the driver for it.

I tried this using TeX Live; since the TL release, PGF has been  
updated and the latest release should work automatically with xetex.  
So another option would be to update your packages.

(I also note that you're running an older release of xetex, and have  
a number of packages installed in a local texmf tree; it may be that  
updating to a newer distribution overall would be worthwhile.)
