Yup, we need to do the same thing in automated testing. Especially when
you're doing lilo -R, and don't know if you ended up fscking or panicing
during attempted reboot to new kernel.

Better would be a checksum of the vmlinux vs the running kernel text,
but that seems to be impossible due to code rewriting. Could we embed
a checksum in a little /proc file for this?
