Original post: FWIW, I have been utterly unable to pair a new Stowaway Sierra with my new N800 running OS2008. See https://bugs.maemo.org/show_bug.cgi?id=2640

EDIT: My mistake. When I tried the technique shown in the above thread (in comment #21), or (equivalently) here:
http://maemo.org/news/announcements/...08_update.html, and also paid attention to the timing of typing in the BT passkey, it worked fine! Still hardly consumer-friendly, but at least it does seem to work.
