i386, hpcmips, and arc were the ports which, at the time of that
writing, use the PC-world MBR partitioning, and hence have RAW_PART as
"d" rather than "c", because of the discrepancy beteween the "entire
disk" partition and the "my MBR slice" partition. See each port's
include/disklabel.h file for the RAW_PART definition.

At this point, bebox, cobalt, hpcmips, and possibly sh3 should be
added to that list, and sgimips is doing something else entirely (the
"k" partition?).

Apparantly the Tahoe had 0 for the RAW_PART equivalent, but I doubt
that bit of history needs to live on in our disklabel man page.
