Just went through Nvidia's readme and looked at the known issues and
found :
We have added checks to recognize that the NVIDIA kernel
module is being compiled for the x86-64 platform on a kernel
between 2.6.0 and 2.6.11. In this case, we will disable
usage of the change_page_attr kernel interface. This will
avoid the accounting issue but leaves the system in danger
of cache-aliasing. Cache-aliasing can lead to data corruption
and random system lockups, but does not consistently reproduce.
I'll be compilin' a 2.6.11 kernel and see if that helps.
