Its about normal. On all linux versions I have used, the nvidia driver required with different kernels was different, and each required its own kernel patch besides the driver. When you upgrade, you are changing the kernel, so a different nvidia driver and another patch would be required. The old nvidia driver causes a protection fault. X aborts and restarts over and over. Some versions of linux detect and stop the endless loop. Others do not. You have to get into a working linux prompt and install a new nvidia driver from NVIDIA. Otherwise you can use the minimally functional nv driver that comes with the distribution by editing XFree86config (or -4), putting nv for nvidia.
