You probably meant loader.rc? Very simple:
load -n3 /kernel /kernel.1 /kernel.2
This will load kernel out of 3 pieces - they could be either /kernel,
/kernel.1 and /kernel.2 or /kernel.gz, /kernel.1.gz and /kernel.2.gz
or any combination of those. Just as an example I've split stock
kern.flp image from 4.5-RELEASE into two images - they could be
downloaded from http://people.freebsd.org/~sobomax/kern.flp.bz2 and
http://people.freebsd.org/~sobomax/kern1.flp.bz2.;
