git-clone http://www.inf.ufpr.br/ribas/repos/vga-module.git

for more info about the code, please see

And yes, unfortunately we will need to keep the RAC module together with 
the VGA arbiter inside Xorg for some time due the portability of Xorg. 
Probably let autoconf set if Xorg needs RAC or the arbiter depending the 
OS would be fine and easy to do.
