All,
I tried to update my 2.4.2 kernel to the latest but there is a dependency conflict with my nvidia graphics card.
There is a graphics driver for the updated kernel but I'm guessing I need to update the kernel before the driver otherwise they'll be a dependency conflict in the other direction.
Don't update kernels. Just install them. That should solve the first dependency error, since the old kernel will still be there.
Then reboot to single user mode to install the new NVIDIA driver.(download it befor you reboot :)
