No, you only can subpartition one partition.  You don't get the minor device 
numbers for more than that.
I would attempt only 6 (or 7) filesystems on one disk.  Three (root, tmp, usr)
on the active partition, and one each one the other 3 (You only have 4 total)
inactive partitions.  I'm not sure putting a file system in the swap 
subpartition is a good idea, and would be impossible on the first drive.

WARNING: Microport only knows what will happen to a bad block on an
inactive partition.

See WN(7).  0s0, 0s2, 0s3, 0s[6789] (or 1s0, etc.). They should already
exist.
