Well, this seems very logic from this point of view... and interesting :)

You are forgetting that FreeBSD is on disk wd0 and NetBSD on wd1. And I've
checked and both OS'es have their MBR slice type setup properly. Remember
that I don't have a NetBSD disklabel on the first disk, nor a FreeBSD
disklabel on the second one (though FreeBSD is able to read NetBSD
Any help will be appreciated! ;)
