NetBSD/arm32, and most UNIX-ish systems, use the 'c' partition as the
raw partition.  NetBSD/i386, for historical reasons, uses the 'd'
partition.

There's not much you can easily do about this.

However, you can make your life easier by using the RAW_PART #define.
it's the partition number of the raw partition.  (on i386, it's 3, on
arm32 and many others, it's 2.)

don't forget, not all ports have 8 partitions, either.  some have 16
(And more will be moving that direction over time.)
