[SOLUTION] … bnep module in 2.6.27 fails to provide bnep0 device
From a thread in linux-bluetooth@vger.kernel.org where i originally posted troubles getting a working pand connection from my laptop to a mobile phone as a tethered 3G modem. Everything worked in the linux kernel-2.6.26 but was broken in >=kernel-2.6.27
With a new phone months later i finally got it working on post 2.6.26 kernels.
I did try posting to back to the list but it's not coming through (whether my subscription is dead or the thread was too application level for list's intention i don't know, and don't care) - but the reply is here for anybody that cares.

C901. I get the same behaviour but have found by luck a work around.If i "Browse files on device..." (using gnome's bluetooth-applet) and
connect to my phone (establishing, via obex, a bluez connection)AND THEN run
pand -c <bdaddr>everything works fine, and it played well with NetworkManager.To simplify, now that i know, I can just run:
hcitool cc <baddr> && pand -c <bdaddr>The successful system log looked like:> Jun 25 15:30:31 [pand] Connecting to 00:25:E7:0D:5E:6D
