Not really, but you can test stuff out manually if you want...

1) get your BT address
2) pair the devices
3) sdptool browse <btaddr>
4) from the sdptool output, find the channel that DUN uses
5) rfcomm connect hci0 <btaddr> <channel #>

and it'll tell you what serial device it just made.  Then you open that
up in minicom and try something like "ATI" and see what happens.

If that all works, then the problem is likely in bluez or NM, not the
kernel.
