I assume this is not an i386 system.

"It's just not done" because many parts of the utilities assume/require
partition c to be the whole disk. disklableing would become a pain if
there were no c partition. :-) Disklabel reading could also get hosed.
Additionally, a number of "whole disk" operations are only suported on
partition c.

Look in the sys/dev/scsipi stuff, and in your architecture's area.

Take care,
