I have had difficulty using the CUDA development driver versions with
the rt-kernel.  That version requires having some locks in the kernel
that aren't allowed in the rt-kernel (my synopsis--might not be
entirely correct).

I only use the proprietary nvidia module with non-rt kernels, and I
use nv or nouveau with rt-kernels.  I will be interested to know if
other people know how to use the proprietary nvidia kernel module with
an rt kernel.
