I think this is starting to look like a problem with the GPU IRQ... With
the non-working drivers, does a simple GL app such as glxgears work? If
not, does it work with the environment variable vblank_mode=0? Do the
radeon numbers in /proc/interrupts increase before/after the problem
occurs? If they don't, does any of the IRQ related kernel boot options
such as noapic, pci=nomsi, ... help?
