cd /usr/src
make KERNCONF=WHATEVER buildkernel
make KERNCONF=WHATEVER KODIR=/boot/kernel.new installkernel
nextboot -k kernel.new
reboot

That will install the new kernel into a separate directory, and will cause 
the next boot *only* to use the new kernel.  If things fail, you just 
reboot, and it goes back to the old kernel.  If things work, then it's a 
simple rename of the kernel directory:
  cd /boot
  mv kernel kernel.old
  mv kernel.new kernel
  reboot

KODIR and nextboot are very handy ... especially for remote upgrades.
