Mounting OpenBSD-format hard disks on 5.0.2?

[Ron McDowell <rcm%fuzzwad.org@localhost>]

Hi, I have 2 USB external hard drives that were newfs-ed [no extra 
options] on an OpenBSD 4.4 system, that have worked fine for me on both 
OpenBSD and FreeBSD systems.  I'm a newcomer to NetBSD, and can't get 
them mounted.  Any ideas?
