take a look at /usr/include/machine/disklabel.h It has the line
#define RAW_PART 2
which says that the "raw" partition (the whole disk) is the partition
number 2. 0==a, 1==b, 2==c I am not sure if this definition is used in
the kernel for all architectures, check also 
/sys/arch/your_arch/your_arch/disksubr.c The include file from the
system directory should be good enough for your boss.
