I remember encountering this recently. X would screw up any time I
tried to access any thing using open GL. I had recently upgraded the
X server so I rebuilt the nvidia-driver port. After that it was all
good. The difference was I could also ssh into it and kill X and
restart it. I found it was usually chewing up nearly a hundered
percent of the CPU time when this happened. In the area of hardlocks,
I have not seen those since several revisions ago.
