I'm not sure if that will be enough to chroot to a 64-bit system, but I suspect it will NOT.
I had assumed you wanted to run a 64-bit kernel on 32-bit userspace. Using the 64-bit kernel from systemrescuecd is definitely good enough to chroot. Either way, you still need to find a working kernel config. Generally, keeping at least current and previous kernels is always a good idea. ĸen -- I live in a city. I know sparrows from starlings.
