<pre>It seems the patches to force Radeon cards into PCI-mode (or force it via
radeon.agpmode=-1) are no definitive solution. My G4 and G5 Macs hold out
longer running X but sooner or later a hard lock is unavoidable. Tested this on
a recent software stack: 4.8.1-kernel, xorg-server-1.18.4, xf86-video-ati-7.7.1
and mesa-12.0.3.
