It's fairly easy to do, if you have a good understanding of what freebsd
is looking for "at install time" and "at bootup time".
If you want a simple recipe which should work, try the following:
Decide which version of freebsd you want to have first in the
layout on the physical disk, and which you want to have second.
Decide what sizes you want for both.
Start to install the version you wish to have *second* on the
disk. In the "fdisk" step, create two slices. Create the
first slice the size you want for the first version of
freebsd, but mark that as a 'DOS' slice (or probably
anything except a freebsd slice). Create the second slice
the size you want for the second version of freebsd, and
leave that defined as a freebsd slice.
Continue on through the installation, putting all the partitions
for the second system in that second slice. Note that when
you get to the 'disklabel' step, it will only show you the
second slice, because the first slice was not marked as a
freebsd slice. So, just finish off this installation as if
it were the only thing you were installing.
Now go back and install whichever version you want to be first
on the disk. In the fdisk step, just switch the slice-type
from 'DOS' (or whatever you used) to 'FreeBSD'. Do not do
anything to that second slice, which already has a version
of freebsd installed in it.
In the disklabel step, only create new partitions from the first
slice. It is probably best to ignore all the partitions
which are already defined in the second slice if you do not
have a good idea of what is going on. On the other hand, it
is mighty tempting to use the same swap-partition for both
systems, so you might want to have the second installation
use the swap partition from the first install.
Continue on through the second installation.
This should give you two separate freebsd systems, which you can
switch between at bootup time.
