Kernel panics with “Cannot open root device” error, where do I append the “root=” option?

I updated Ubuntu 2 days ago and now I can't login, even in Safe Mode, since there's a Kernel Panic ('VFS not syncing', something like that). I know this is a bug but I don't want to reinstall everything again. Is there some way to make Ubuntu functional again? The problem too is that I don't have old kernels on my GRUB list, since it seems the update erased all of them.

Here's a picture of the kernel panic at boot: enter image description here

We need far more information about the panic really, even if its just a photo of it :) – Caesium Nov 27 '11 at 23:27

I had the same issue. I chose older versions instead of safe mode at boot and selected the previous kernel Now the system runs fine, but at next boot, will again be the default. Therefore, I removed the all kernel packages found with the string "" in synaptic package manager.
