Well, the actual partition number doesn't really matter.  What you need to
do is use the `disklabel' command to see what the NetBSD partitions are,
and then match things up with your Mac partioning utility's info.   As far
as I remember, /dev/sdxc is always "the whole disk", /dev/sdxa is always
the first Root or Root&Usr partition, if any, /dev/sdxg is always the
first Usr partition, if any, and /dev/sdxb is always the first swap , if
any.  I've also found that /dev/sdxd usually ends up being the Mac Driver
partition, pretty much useless under NetBSD.  All other partitions are
assigned in alphabetical order, using whatever letters (between a and h)
are left.

"First" in this case means tht it is listed nearer to the beginning of the
disk's Partition Map partition.  It isn't _necessarily_ the partition
nearest to the beginning (Cylinder 0) of the disk!  :)
