Pname is the reason the device node is missing in the first place :-)

If you use HDSC Setup (or if SilverLining does its job right), the slice 3
partition will be the right size to accomodate the rest of your disk when
you set things up.  There is no need to use dp to extend it.  That is, there
will be a partition (slightly > 80MB) on a 160MB disk, all ready to use.

If you have an (older) HD80, you'll see a 1K slice 3 partition.
The reason for this is because we couldn't say "grow from 0 to n".
