Others have already commented that GPT labels are better, but I think
that you can have more than 8 partitions.  I remember a posting a while
back that the maximum had been increased.  You will have to experiment
if you want to do this, but gpart shows an example that uses 20
partitions:  '/sbin/gpart create -s BSD -n 20 ada0s1'.  I also don't
know that bsdlabel will handle these, so you definitely should
experiment first.
