In the past year or so there have been three different published ways to 
build your kernel, so it's understandable that there would be confusion 
here.

Building a new userland often requires building a new kernel. If
you are running FreeBSD 4.2 or later, here is the 'nutshell version'
of the steps:

   make buildworld
   make buildkernel KERNCONF=YOUR_KERNEL
   make installkernel KERNCONF=YOUR_KERNEL
   reboot (in single user)
   make installworld
   mergemaster
   reboot

To simply build a kernel without building world:

   make buildkernel KERNCONF=YOUR_KERNEL
   make installkernel KERNCONF=YOUR_KERNEL
   reboot

In your case, I would have compiled the GENERIC kernel during your
buildworld so you would have a kernel in sync with your userland. If you
didn't experience any serious problems during the build, consider yourself 
lucky.

I believe the above procedures are pretty safe, and they are all
detailed in the handbook.
