Well you can use the d partition, but it doesn't need to take on a
"special" meaning like it may on disks partitioned for multiple operating
systems. Most all of the /etc/disktab entries illustrate relatively
complex partitioning schemes.  I normally follow the following conventions
on my diskful VAXen:

    ra0a  /
    ra0b  swap
    ra0c  whole disk
    ra0d  /var
    ra0e  /usr

Of course, I don't think there's anything which prevents you from
allocating your b and d,e,f,... partitions in novel ways.  I suppose you
could give your b partition sectors which are physically located after
those in your d partition.
