Such a patch would also have to copy the modules (which aren't under kernel26's 'purview'). For example, nvidia gets upgraded on a major version kernel update, the old kernel which has been renamed doesn't 'work' graphically anymore.
Just for keeping an old kernel image as a fallback keeping the modules, too, isn't necessary. The old kernel image is just to get the system booted to being able to repair the system (downgrading the kernel package again or whatever). The modules shouldn't be necessary for this. Nevertheless I would suggest not to keeping an old kernel version when upgrading the kernel. I'm using Arch Linux for about 4 years now and before then I was using Gentoo for about 6 years. I never had one single issue with a kernel upgrade particularly not such an issue which caused a boot failure. If this really happens - in the very rare cases - then it's always possible to boot from a LiveCD. If someone is really so afraid he can easily install kernel26-lts or another kernel package and, of course, he definitely shouldn't use the [testing] repo. I don't see a real reason for keeping an old kernel image after an update. Just KISS. Heiko
