I've never tried this, but I was told it works.  I do know the original 
version of pdisk didn't set the bits in the partition correctly and I 
re-enabled that code when I added the "V" option to format and dump the 
Partition Table.  So make sure you have a good backup before trying 
anything.

It's been a long time since I played with pdisk, but I believe if you set 
the partition name to "Apple_UNIX_SVR2" it will do what you want.  This 
is the partition type that NetBSD looks for, then it checks to see if the 
proper flags have been written to the partition.  This isn't really the 
partition name, it's actually the partition type.  The Partition Name 
field is generally ignored by NetBSD now.  I think at one point 
NetBSD/mac68k searched for keywords in the name field while trying to 
classify the partition.  If you have the option of putting in a name use 
works like "root", "swap" and/or "usr" to classify the partition 
according to the way you want it used.

I may be wrong, but I don't think sysinst/macppc does anything other than 
deal with the whole disk.  There is a version of sysinst that does deal 
with the Apple Partition Map but right now it's only used in the mac68k 
port.  It also allows the entire disk to be used for NetBSD like the 
current version of sysinst/macppc.  There hasn't been a lot of testing 
with it on the mac68k port (other than its been working for me for a year 
or so), but maybe it's about time to start thinking about using it with 
the MacPPC port as well.  It knows how to work around the Apple Disk 
Partition Map, and it has logic to actually partition the disk and 
re-write the Apple Diks Partition Map.

Hope this helps,
