I still think a hardware stress test will be useful. The least that will happen is you will verify your hardware is probably OK. If it is software, then you have a long road ahead of you debugging it. With no error messages of any kind you will likely have to rebuild in debug mode and provide the devs with a backtrace. In which case it's probably easier to downgrade to versions you know work. I can attest to xorg-server-1.7.1 working just fine here with latest nvidia- drivers in the tree on amd64 -- alan dot mckinnon at gmail dot com
