If what you're after is essentially running kernel doesn't match kernel
that will run on next boot, should be a fairly trivial ext script to
compare contents of uname -r to grubby --default-kernel|sed
"s/\/boot\/vmlinuz-//".  That would be how to do it on Red Hat, looks like
you'd also have to massage uname -r for hardy.

Don't know if it's already been done.
