kernel 2.6.13 hangs / freezes with nvidia
kernel module on switch to virtual console

Running Debian testing and stable and built the kernel with the attached
config.  Then the NVidia installer was run.  Everything boots and runs
fine.  X and Gnome come up and run.  Switching to a Virtual Console
locks up the system and shows some crazy colors.

The system ran fine with the same configs until ~kernel 2.6.12.x and has
exhibited this failing behavior since then with multiple kernels.

The graphics card is a shown below and has two outputs both in use for
two monitors.  Thus the actual driver from NV is needed.  I do not
believe the Xfree nv driver supports dual head.
