Keep in mind that this procedure has serious foot-shooting potential.  I 
would not recommend people try this unless the only alternative is a 
reinstall.  If something goes wrong and you can't figure it out, you 
may have to do the reinstall anyway.

I just wanted to reiterate that to make sure that everybody understands 
the situation...

The difficulty is working around the catch-22 situation where you need a 
new kernel first so you can install world, and you need a new world 
first before you can boot the new kernel.  Cheating and using the swap 
partition for a temporary world is one way around it.   It might even 
be necessary to do a new buildworld inside the temporary world if you 
can't reinstall the previous one.  Some creativity will be needed.
