Yes.  Just slice up your disk and use one of the extra slices to install 
your other version.  AFAIK, you need one slice per system because you 
can only boot from the "a" partition is a slice.  You have to use a real 
slice not a logical/extended one.

Or just get an extra disk and install extra system to that.

Of course, you can only *run* one at a time, but you can certainly share 
user data between builds (though any binaries probably require compat 
packages).

This is generally how I upgrade between major revisions.  I have extra 
/, /usr, /var and /usr/local (called /alt, /alt/var...) and I install 
new version to the "alt" partitions.  Then use boot manager to pick 
which to boot.  Once I am happy with the new version I either copy it 
across to the original partitions or just boot the new partitions from 
then on and use the old partitions as the "alt"s.
