You can modify the existing floppy images. boot.flp contains the first 
part of the kernel and kern*.flp the further parts.

Build a custom kernel using

   makeoptions MODULES_OVERRIDE=""

in your kernel configuration file.

   # cd /usr/src/sys/i386/conf
   # config YOURKERNEL
   # cd ../compile
   # make cleandepend; make depend
   # make

Take your kernel file and compress it:

   # gzip -9nc kernel > kernel.gz

Now you can use the 'split-file.sh' script from src/release/scripts to 
split the compressed kernel into parts.

   # /usr/src/release/scripts/split-file.sh kernel.gz destdir 1392 Kernel

You can mount a floppy disk image with the following commands:

   # mdconfig -af boot.flp
   md45
   # mount /dev/md45 /mnt

Replace the kernel parts with your own.

I hope this helps. I havn't tested it before. There are other ways that 
are more elegant.
