Also unless you reboot to the installed kernel, you can't verify that the install worked properly. It would be pretty bad if didn't reboot after an install and find out that a writing error corrupted kernel 3 weeks later during a power outage.
Now it is possible to do a 2 kernel monty to switch kernels on a running system but technically that is still a form of a reboot. It requires all services to be shutdown and causes the system to boot (partial boot as memory isn't cleared) to a kernel in a different memory location than the current running kernel. A two kernel monty is generally used in a big network boot environment to determine which kernel should be loaded (ie Intel/Athlon SMP/NON-SMP.) Now this would still be useless with an install as it doesn't test the lilo or grub install.
