Add an rfcomm device (e.g. rfcomm0) to /etc/bluetooth/rfcomm.conf (make sure to replace the Bluetooth device address 11:22:33:44:55:66 with the Bluetooth device address of your N900): 

/etc/bluetooth/rfcomm.conf
rfcomm0 {
#       # Automatically bind the device at startup
        bind yes;
#
#       # Bluetooth address of the device
        device 11:22:33:44:55:66;
#
#       # RFCOMM channel for the connection (whatever you get from the sdptool output)
        channel 1;
#
#       # Description of the connection
        comment "N900";
}

Restart the bluetooth stack: 

blackbox:~# /etc/init.d/bluetooth restart

For bluetooth pairing you can run 

blackbox:~# cat < /dev/rfcomm0

and first the N900 then the Debian system should ask you for a 4 digit PIN which you define on the N900 and confirm on the Debian system. You might have to configure the helper application which is using the PIN in /etc/bluetooth/hcid.conf

[edit] Dial-Up Settings

Run pppconfig and use /dev/rfcomm0 as the modem interface:

In my settings for klarmobil (Germany) I manually added two lines (at+cdgcont=... and AT+CREG...): 

blackbox:~# cat /etc/chatscripts/klarmobil
# This chatfile was generated by pppconfig 2.3.18.
# Please do not delete any of the comments.  Pppconfig needs them.
#
# ispauth PAP
# abortstring

# ispconnect
CONNECT \d\c
# prelogin 
 
# ispname
# isppassword
# postlogin
 
# end of pppconfig stuff
blackbox:~#

In my peers file I changed the baud rate to the device 

blackbox:~# cat /etc/ppp/peers/klarmobil
# This optionfile was generated by pppconfig 2.3.18.

For ifupdown integration add to /etc/network/interfaces 

iface ppp0 inet ppp
 provider klarmobil
