Nothing specific, but just by way of general brainstorming, I
wonder what the two kernels are, what the modules or built-in
drivers are.  Can you run the userland of the one with the
kernel and modules of the other (should only take copying the
vmlinuz, initrd, and /lib/modules/kernel-foo/ directories into
the appropriate places, and setting the boot loader up)?
