Problem with radeon + AIGLX

[Andrew Turner]

When I enable AIGLX in xorg.conf with xorg-7.2 the system locks up, to
the point I have to use the reset button, with a blank screen. By
removing AIGLX from xorg.conf allows xorg to start.

From the little information I've managed to retrieve from the system it
appears the drm ioctl is returning EINVAL causing the video driver to
enter into an infinite loop. I also got an error similar to kern/112984
indicating there is a locking problem.
