It's never a good idea to do an installworld before building (and installing)
the new kernel. Don't do this. I think you are referring to the 20040728
entry in UPDATING, which reads:

        With the upgrade of the system compiler, the kernel has been upgraded
        to match the new system compiler.  This makes it impossible to build
        a new kernel with the old compiler.  Upgrade your system via
        make buildworld and make kernel (see below) to fix this problem.

This clearly states that you *can* build the kernel *after* you do a make
buildworld. It does *not* say you have to do an installworld.
