Lo mejor es que quien lo subió comenta que funciona en "debian testing" lo mismo que uso, además que funciona relativamente bien.
Los pasos son;
1.- Usé el siguiente parche para el driver de nvidia (nvidia-304.88_linux-3.10.patch).

Pueden ver el parche.
2.- Aplicar el parche al driver
./NVIDIA-Linux-x86-304.88.run --apply-patch nvidia-304.88_linux-3.10.patch
Esto creará una modificación del driver que se llamará "NVIDIA-Linux-x86-304.88-custom.run", este último es el que se instalará.
En mi caso la instalación funciono sin novedad, y el vídeo funciona igual que antes, hasta ahora sin problemas.
