You don't need to do anything to enable aiglx, just removing xgl should
work. "sudo apt-get remove xserver-xgl", though in ubuntu you can create an
extra file, and it will just not start xgl, which will have the same effect
(I am just not sure which file that is). Also, compiz won't work with that
card and the open drivers, so you will have to use fglrx. (just uninstall
xgl and see if the performance increases)
