So, for the records:
I have 2 HFS+ and one UFS partitions, ofwboot.xcf sits in the first HFS+ one - the MacOS X system partition, NetBSD lives happily in the UFS partition. Booting it is simpler than I thought - just boot hd:,\ofwboot hd:7/netbsd - this loads ofwboot from the first partition and the kernel from the UFS one which happens to be wd0g for NetBSD :)
( and yes, root at wd0g is in the kernel config ).
There's no swap partition, but the iBook has 640MB RAM, I have other machines with less virtual memory, so it's pretty unlikely to really need one anyway.

So, now let's tackle this pesky XFree problem...

have fun
