No, you should split /dev/hda6 into at least 3 additional partitions to
create a root, swap and usr partition. You can place ofwboot.xcf into
your OSX root partition. With NetBSD pdisk you can set the bzb bits for
root (a) and user (g) partition you'll need for newfs'ing the
partitions. Use the pdisk for NetBSD after booting the NetBSD/macppc CD
through fetching it via ftp into /sbin. You'll need to pdisk /dev/wd0c
(not /dev/wd0).

After you've successfully installed NetBSD you can boot it from OFW as
follows (assume OSX is your partition #7, and the kernel of NetBSD
resides in the 6th "Apple_UNIX_SVR2" partition):

boot hd:7,ofwboot.xcf hd:6,/netbsd

I don't know if NetBSD is capable to read Apple-alike ext2 partition maps.

Have also a look into my HOWTO under:
